GENERAL INFORMATION
1-1 INTRODUCTION
1-2 This instruction manual contains operating and
service instructions for the HP-IB Isolated D/A Power
Supply Programmer Model 59501B,. Installation instructions
and sample programs are also provided. The 59501B
allows HP power supplies to be digitally controlled via
the Hewlett-Packard interface Bus (HP-IB) from a calculator,
computer, or other controller. The digital format is bit
parallel, byte serial, ASCII coded format. The 59501B
can also be used on the HP-IB as a digitally programmable
low level dc signal source. Since the 59501 B ! can be
controlled (programmed) by various control devices such
as HP 9800 desk-top computers, hereafter in this manual,
the controlling device will be referred to as the "con¬
troller”, except when specific programming examples are
provided.
1-3 DESCRIPTION
1-4 The 59501B'. is basically a digital-to-analog (D/A)
converter that provides an output voltage in response to
digital data received on the HP-IB. Two programmable
output ranges (IV and 10V) are available. In addition, a
switch on the rear panel allows selecting either a unipolar or
bipolar output mode. The unipolar mode provides a 0 to
,999V or a 0 to 9.99V output range and the bipolar mode
provides a —IV to +0.998V or a —10V to +9.98V output
range. The 59501 B's output can be used as a programming
voltage for controlling a wide range of dc voltages and
currents from HP power supplies or as a source voltage for
testing electronic components such as integrated circuit
packages (IC's).
1-5 Isolators within the 59501B protect other instru¬
mentation on the HP-IB from damage that could be caused
by power supply outputs. Also, an internal circuit ensures
that the output is held near zero until programmed data is
received. Power supply programming is accomplished
through use of the 59501 B's programmable output voltage
and its front panel adjustments. By making the appropriate
connections between the 59501 B's rear terminals and the
programming terminals on the supply, the output voltage
(or current, if available) of the power supply can be
programmed from zero to its full rated output. The
59501 B's front panel adjustments provide fast and easy cali¬
bration of power supply outputs. The ZERO ADJUST
enables the user to correct for small offsets in power supply
response to programmed inputs. The POWER SUPPLY
FULL SCALE ADJUSTMENT (COARSE and FINE)
allows the user to set the maximum output desired from the
power supply when the 59501B is programmed touts
maximum output. This method of programming is called
voltage programming with gain. Power supply program¬
ming is described in greater detail in Section III.
1-6 Programming the 59501B is accomplished through
the transmission of four consecutive digits (four ASCII
characters). The first digit specifies output range and the
next three digits specify the magnitude within the selected
range. The high/low range capability provides a ten to one
improvement in resolution. Internal conversion circuitry
enables the 59501B to produce its maximum output voltage
in approximately 250^sec from the time the digital data
is received. Output current up to 10 milliamps is available
and is automatically limited to protect the 59501B and
the user equipment.
1-7 HP-iB CAPABILITIES
1-8 The 59501B has'listener" and "acceptor hand¬
shake” HP-IB functional capabilities. The LISTENING
indicator on the front panel provides a convenient means of
monitoring the 59501 B's operating status. The 59501B
does not have: controller, talker, source handshake, service
request, device trigger, extended listener, extended talker,
parallel poll, and remote/local HP-IB functional capabilities.
All HP-IB functional capabilities are described in IEEE
Standard 488-1975.

source. A printed circuit board located within the ac
power module on the rear panel selects the power source.
Voltage choices are available on both sides of the PC
board. Before connecting the instrument to the power
source, check that the PC board selection matches the
nominal line voltage of the source. The operating voltage
that is selected is the one printed on the lower-left side
of the PC board (see Figure 2-5). As shipped from the
factory, the PC board in this unit is positioned for 120Vac
operation. To select another input voltage proceed as
follows:
a. Remove power cable from instrument.
b. Move plastic door on power module aside.
c. Rotate FUSE PULL to the left and remove line
fuse FI.
d. Remove PC board from slot. Select operating
voltage by orienting PC board to position the
desired voltage on top-left side of PC board. Push
board firmly into slot.
e. Rotate FUSE PULL back into normal position and
re-insert fuse FI in holder using caution to select
the correct value for FI (125mA for 100V or 120V
and 62.5mA slo-blo for 220V or 240V)..
f. Close plastic door and connect power cable.
2-29 When the instrument leaves the factory, a 125mA
fuse is installed for 120V operation. An envelope contain¬
ing a 62.5mA fuse for 220V/240V operation is attached to
the instrument. Make sure that the correct fuse value for
FI is installed if the position of the PC board is changed.
2-30 Power Cable
2-31 This unit is factory equipped with a power cord
plug that is the most appropriate for the user's location.
The replaceable parts section of this manual lists all of the
power cords associated with this unit. If a different power
cord is desired, contact your nearest HP Sales Office.
2-32 To protect operating personnel, the National
Electrical Manufacturers Association (NEMA) recommends
that the instrument panel and cabinet be grounded. This
instrument is equipped with a three conductor power cable.
The third conductor is the ground conductor and when the
cable is plugged into an appropriate receptacle, the instru¬
ment is grounded. The offset pin on the power cable three-
prong connector is the ground connection. In no event
shall this instrument be operated without an adequate
cabinet ground connection.
2-33 To preserve the protection feature when operating
the instrument from a two-contact outlet, use a three-prong
to two-prong adapter (if permitted by local regulations) and
connect the green lead on the adapter to ground.

SECTION III
OPERATING INSTRUCTIONS
3-1 INTRODUCTION
3-2 This section contains operating instructions and:
programming information for the 59501B isolated DAC,
Power Supply programmer. Since the 59501B can be used
as a power supply programmer or as D/A converter (low
level dc signal source), operating instructions and program¬
ming examples are provided to cover both applications.
Additional information regarding use of the 59501B is
provided in HP-IB/Power Supply Application Guide, HP
Part No. 5952-3990.
3-3 PRE-OPERATIONAL CONSIDERATIONS
3-4 Before connecting the 59501B to an ac power
source, ensure that the proper operating voltage (100, 120,
220, or 240Vac) has been selected and the proper fuse is
installed (see paragraph 2-27). Also, check that the address
switches are set correctly, the UNIPOLAR/BIPOLAR mode
switch is set to the desired position, and all HP-1B system
cabling is installed (see paragraphs 2-20 through 2-26).
Connections between the 59501B and the user's device
(e. g. HP Power Supply) are described in subsequent para¬
graphs.
3-5 CONTROLS AND INDICATORS
3-6 Front Panel
3-7 . The 59501B front panel contains a power on-indi¬
cator, a status indicator and four controls (screwdriver ad-‘
justments) as shown in Figure 3-1.
3-8 The power on (ON) indicator (?) (Figure 3-1)
lights and the 59501 B's internal supply voltages (+15V,
±15V, V dc j) are present when the line cord is plugged-in.
3-9 The LISTENING indicator (J) lights when the
59501B is addressed to ''listen'' and remains lighted until
an "unlisten" command or the interface clear signal is
received from the controller. When lighted, it indicates that
the 59501B is enabled to process data words received on
the HP-IB. When it is not lighted, it indicates that the
59501B is inhibited from processing data words.
3-10 The front panel screwdriver adjustments allow fast
and easy calibration of D/A and power supply outputs.
Each adjustment is described below.
3-11 The ZERO ADJUST (5) allows the 59501B out¬
put to be adjusted to 0V ± 250 millivolts when it is program¬
med to zero output. It can also be used to correct for small
offsets in power supply response to programmed inputs when
the 59501B is used as a power supply programmer.
3-12 The D/A FULL SCALE ADJUST @ allows the
59501B output to be adjusted to maximum (±5%) when it
is programmed to maximum. For example, if the 59501B
is programmed to its maximum unipolar output in the high
range, the D/A FULL SCALE ADJUST is normally used to
set the output to 9.99V. However, it can also be used to
set the output between 9.49V and 10.49V (i. e. 9.99V ±5%).
The D/A FULL SCALE ADJUST is used when the 59501B
is employed as a D/A (see paragraphs 3-73 through 3-80).
When the 59501B is used as a power supply programmer,
the POWER SUPPLY FULL SCALE ADJUST controls are
utilized to set the power supply's output.
3-13 The POWER SUPPLY FULL SCALE ADJUST
controls (COARSE and FINE) (S) enable the user to
set the maximum output desired from the power supply
when the 59501B is programmed to its maximum value.
These adjustments can be used to calibrate the output of a
power supply to its maximum rated output or to any lower
value. For example, a 40Vdc power supply's output could
be set to 20V when the 59501B is programmed to its maxi¬
mum value. In this case, all 999 programming steps are
utilized in programming the supply from 0 to 20V with a
resolution of 20mV (approx.). Calibration of power supply
outputs is described in paragraph 3-51 through 3-57.

3-14 Rear Panel
3-15 The 59501B rear panel contains the HP-1 B connec¬
tor, the ADDRESS switches, the UNIPOLAR/BIPOLAR
mode switch, the ac power module, and the output term¬
inal strip as shown in Figure 3-2.
a. HP-IB connector — Interfaces directly to HP-IB
(paragraph 2-17).
b. ADDRESS switches — Select ''listen'' address of
59501B (paragraph 2-22).
c. UNIPOLAR/BIPOLAR switch - Selects either
the unipolar of bipolar output mode (para¬
graph 2-25).
d. Ac Power Module — Contains fuse and ac input
voltage select PC board (paragraph 2-27).
3-16 The 59501B is interfaced with the user's device
via the output terminal strip. Output terminals A1 and A2
allow access to the 59501 B's D/A output while terminals
A3 through A5 allow access to the power supply program¬
ming network. Figure 3-3 illustrates the connections re¬
quired to program the output voltage of a typical HP power
supply. In this case, a jumper is connected between termin¬
als A2 and A3, and terminals A1, A4, and A5 are connected
to the voltage programming terminals of the power supply.
The method of programming and the connections required
to program the output voltage or current of various HP
supplies are described in paragraphs 3-35 through 3-72.
When the 59501B is used as a low level dc signal source,
only terminals A1 and A2' are connected to the user's device.
Programming instructions for this application are given in
paragraphs 3-73 through 3-80.

3-17 PROGRAMMING FUNDAMENTALS
3-13 The unipolar or bipolar output of the 59501B is
programmed by a data word comprised of four ASCII
characters (digits) received in the order shown below. The
first digit specifies range and the next three digits specify the
desired output within the selected range. The range digit
must be the number 1 to specify low range or the number 2
to specify high range. The magnitude digits can be any
number from 000 to 999.
D1 D2 D3 D4
/
Range Magnitude
1 or 2 000-999
3-19 The 59501B automatically provides an output
voltage as soon as the four digits are received. This output
is retained until the next four digits are received. The
59501B is programmed by the magnitude digits in BCD to
produce the desired output voltage. In the unipolar mode,
000 equals 00.0% of full range, 500 equals 50.0% of full
range; and 999 equals 99.9% of full range. In the bipolar
mode, 000 equals the maximum negative voltage output,
500 equals 0V output, and 999 equals the maximum positive
voltage output.
3-20 Calculating Data Word Values
3-21 The following paragraphs describe the data word
value calculations required to program the output of the
59501B. Similar calculations are required when program¬
ming power supply outputs using the 59501B. The pro¬
grammable output range depends, of course, upon the power
supply model being programmed. The desired output range
of the particular power supply must be calibrated for pro¬
gramming with the 59501B. Power supply calibration pro¬
cedures and sample programs are described in paragraphs
3-51 through 3-72.
3-22 Data word value calculations for the high (10V)
and low (IV) 59501B output ranges are described below
Calculations are provided for both the unipolar and bipolar
output modes. Each data word must be exactly four digits
3-2

long (one digit for range and three digits for magnitude). If
more than four digits are sent to the 59501B, the desired out¬
put voltage will not appear at the output.
3-23 Unipolar Mode
3-24 Low Range. The desired 59501B output voltage
values are from 0 to 0.999V programmable in 999 steps.
The resolution in this range is equal to .999V/999, or ImV
per step. To calculate the correct data word value to pro¬
duce the desired output within this range, proceed as
follows:
1. The resolution in the low range is ImV,
Let D = .001
2. The range digit is 1 for the low range, so add 1
to the left of the 3 magnitude digits,
Let R = 1000
3. The magnitude portion (M) is calculated by
dividing the desired output voltage (V) by the
least significant digit D. The magnitude portion
must be rounded off to exactly 3 digits,
M = INT (V/D + 0.5) = 3 magnitude digits
4. Combine range and rounded off magnitude
portion to obtain the correct data word value (N),
N = R + M
Example, desired voltage = 0.5123V
D = ,001
R = 1000
M = INT (0.5123/.001 +0,5)
M = INT (512.8)
N - 1000 + 512
N = 1512 = data word value
In this example, the desired output voltage is 0.5123 volts
but the actual output is 0.512V because the resolution is
ImV (least significant digit equals .001):
V = M x D
V= 512 x .001
V = 0.512
3-25 High Range. The desired 59501B output voltage
values are from 0 to 9.99V. The calculations are the same
as for the low range, except resolution is lOmV and the
high range is used. For the high range,
Let D - .01
and R = 2000
3-26 Bipolar Mode
3-27 Low Range. The desired 59501B output voltage
values are from -IV to +0.998V programmable in 999
steps. For a —1V output, the magnitude digits are 000 and
for a +0.998V output, the magnitude digits are 999. A 0V
output is obtained when the magnitude digits are 500.
Resolution in this range is equal to 1.998/999, or 2m V. To
calculate the correct data word value to produce the desired
positive or negative output voltage within this range, pro¬
ceed as follows:
1. The resolution in the —IV to 0.998V range is 2mV,
Let D = .002
2. The range digit is 1 for the low range, so add 1
to the left of the three magnitude digits,
Let R = 1000
3. The magnitude portion (M) is calculated by
adding 1 to the desired negative or positive out¬
put voltage (V) and dividing this sum by the least
significant digit D. The magnitude portion must
be rounded off to exactly 3 digits.
M = INT (V + 1 )/D + 0.5)
4. Combine range and rounded off magnitude pot-
tion to obtain the correct data word value (N),
N = R + M
Example, desired voltage = -0.5123V
D » .002
R = 1000
M = INT (-5.123 + D/.QG2 + 0.5)
M = INT (+0.4877/.002 + 0.5)
M = INT (243.85 + 0.5)
M = INT (244.35)
N = 1000 + 244 = 1244
In this example, the desired output voltage is -0.5123V
but the actual output is —0.512V because the resolution is
2mV (.002):
V = (M x D) -1
V = (244 x .002) - 1
V = 0.488 ~ 1
V = -0.512 V
3-28 High Range. The desired output voltage values are
from —10V to +9.98V. Calculations are similar to those
for the low range, except resolution is 20mV on the high
range, and 10 must be added to desired positive or negative
output voltage in order to calculate the correct magnitude
digits. For this range, the equation for the magnitude
portion (M) of the data word value is:
M = INT ((V + 10)/D + 0.5)
Example, desired voltage = -5.123V
D- .02
R = 2000
M = (NT {(-5.123 + 10)/D +0.5)
M = INT (243.85 + 0.5)
M = INT (244.35) = 244
N = 2000 + 244 = 2244
In this example, the desired output voltage is -5.123V but
the actual output is -5.12V because the resolution is 20mV
(. 002 ):
V= (M x D) -10
V = (244 x .02) -10
V = 4.88 - 10
V = -5.12V

3-23 Sending Data Words
3-30 Before a data word is sent, a command must be
issued establishing the controller as the ''talker'' and the
59501B as the''listener''. The following examples assume
that the controller (9825A calculator) has been assigned it stan¬
dard talk and listen addresses of "U" and "5” respectively, and
the 59501B has been assigned a listen address of
3-31 Example 1 illustrates a command statement issued
by a 9825A calculator. Note that in addition to the
calculator talk address "U" and the 59501B listen address
the address code of the HP-IB Interface Card
(98034A) must be included. It is assumed that the interface
card has been assigned its standard select code of "7".
The 9825A command statement also includes a constant
data value of ”1250" which is sent to the 59501B.

3-32 Example 2 illustrates a write statement (9825A
calculator) which can also be used to address the 59501B
to listen and send a constant data value. The 59501B- listen
address of corresponds to an address of "06" as defined
in the 9825A General I/O ROM manual (09825-90024)
Chapter 4. Note the format statement (line 0) used in
Example 3. The "c" specifies a character field, while the -
"z" is used to suppress carriage return/line feed codes at the
end of the write statement. Suppression of the carriage
return/line feed codes is essential when programming the
59501B . If they are not suppressed, they will be processed
as data characters by 59501B resulting in an undesired
output.

3-33 Command statements can only be used to send
data constants. Write (9825A) statements can be used to
send data constants but must be used to send variables.
3-34 Example 3 illustrates how a write statement (9825A)
is used to send variable data to the 59501B . If variable N in
line 1 were equal to 1250, this example would program the
same output as the previous examples. Format specification
f4.0 deletes leading spaces and the z suppresses the CR/LF
codes for the same reasons as described above.

3-35 USING 59501B AS A POWER SUPPLY
PROGRAMMER
3-36 Power supply programming is accomplished using
the digitally controlled output voltage of the 59501B in
conjunction with the ZERO ADJUST and POWER SUPPLY
FULL SCALE ADJUST controls on the 59501B front panel.
By making the appropriate connections between the
59501 B's output terminals and the voltage programming
terminals of a dc power supply, the output voltage (or cur¬
rent) of the power supply can be programmed from zero to
the full rated output. This method of programming is
called voltage programming with gain.
3-37 Voltage Programming With Gain
3-38 HP programmable power supplies have certain
features in common. These features include: an internal
reference (either a fixed regulated voltage or a fixed regu¬
lated constant current source), voltage and current compara¬
tors with their input terminals, and front panel controls
(voltage and current) with connections at the rear panei
terminals. A power supply can be controlled by making
the appropriate connections on the rear panel and applying
an external voltage (or in some cases current). For example,
by disconnecting the internal reference voltage from the
input circuits of the constant voltage comparator and
replacing it with an external voltage source, the output
voltage of the power supply is programmed by the value of
the external voltage source.
3-4

3-39 Figure 3-4 illustrates the method by which a power
supply’s constant voltage output can be programmed using
an external voltage with a voltage gain dependent upon the
ratio of Rp to R R . Note that this method is no different
from the circuit normally used for constant voltage control
of the output except that an external reference (the pro¬
gramming voltage source) has been substituted for the
internal reference. On most supplies, external terminals
are available so that the connections shown in Figure 3-4
can be accomplished without any internal wiring changes.
In all HP remotely programmable power supplies, the
summing point S is made available, and the configuration
of Figure 3-4 can always be accomplished using the external
programming voltage source E p and external precision wire-
wound resistors Rp and Rp. (Rp should not exceed 10k;)
As indicated by the equation in Figure 3-4, R p can be
selected so that the resulting voltage gain is either less or
greater than unity. It is possible to use the front panel
control on the supply as the voltage gain control R p .
Figure 3-4. Voltage Programming with Variable Voltage Gain
3-40 Constant Voltage. Figure 3-5 illustrates the con¬
nections required for the 59501B to program the constant
voltage (CV) output of a typical HP power supply. Note
the similarities between Figures 3-4 and 3-5. The 59501B
includes R R (R76), R p (COARSE and FINE POWER
SUPPLY FULL SCALE ADJUST), and E p { 59501B.output
between terminals A1 and A2). The extra resistor (R77)
between terminals A5 and A6 is used only when program¬
ming power supplies above 300 volts.
3-41 As shown in Figure 3-5, the supply's internal
reference voltage (+V R E p ) and VOLTAGE control are
disconnected (dotted lines) and are replaced with the
59501 B's output voltage and POWER SUPPLY FULL
SCALE ADJUST. Note that in the unipolar mode, 59501B
output terminal A1 is negative with respect to A2. This
polarity must be complied with when making connections.
The connections shown in Figure 3-5 are typical for most
supplies.
3-42 Constant Current. Figure 3-6 illustrates the
connections required for the 59501B to program the out¬
put current of a typical HP power supply. Programming
constant current consists of replacing the internal reference
with the output voltage from the 59501B and replacing
the internal CURRENT control with the POWER SUPPLY
FULL SCALE ADJUST controls on the 59501B . With
these connections, the voltage developed across POWER
SUPPLY FULL SCALE ADJUST (R p ) becomes the reference
against which the voltage drop across the output current
monitoring resistor (Ry) is compared. The relationship
between E p and the supply's output current depends upon
the resistance ratio R p /R p a nd on the constant current pro¬
gramming coefficient (K p ) of the particular supply. The
relationship between input voltage and output current is,

Figure 3-8. Typical Connections for CC Programming
3-44 Table 3-1 lists the HP Power Supplies that can be
programmed on the HP-IB using the 59501B. The table
specifies if a supply is capable of CV and/or CC programming
with the" 59501B and also lists the applicable 59501B/power
supply connection diagram. The accuracy of a power supply/
59501B combination is the sum of the 59501B's accuracy
plus the accuracy of the particular power supply. 59501B
power supply programming accuracy specifications are given
in Section I.
NOTE
One 59501B can only program a supply's CV or
CC output. If it is desired to program both CV
and CC on the HP-IB, two 59501B's are required
with their address switches set to different addresses.
3-45 The leads (AWG No. 24, minimum) connecting the
59501B to the power supply should be twisted to reduce
noise pickup. The longer the connecting leads, the more noise
that can be introduced. Shielding will further improve noise
rejection. After completing the connections, install the pro¬
tective covers over the terminal strips on the 59501B and
on the supply.

3-46 CV Programming Connections. Figures 3-7 through
3-13 illustrate the connections required to program the CV
output of the applicable power supplies. The dotted line
connections represent jumpers which must be removed. All
other jumpers must be installed as illustrated. Note that
only those power supply terminals pertinent to CV program¬
ming are shown. Complete terminal strip details are pro¬
vided in the appropriate power supply Operating and Service
Manual. Most of the supplies are programmed using the
connections illustrated in Figure 3-7. The specific connec¬
tions for each supply are tabulated on the diagram.
3-47 Special Protection Circuit. As indicated on Figure
3-7, some of the supplies contain a special protection circuit
which must be considered when programming with the
59501 A. The supplies affected are models 6256B through
8274B, 6282A, 6285A, 6286A, 6290A, 6291 A, and 6296A.
Down programming the output voltage of these supplies may
activate the special protection circuit. When this occurs, the
power supply's load cannot draw more than 10% (approx.)
of rated output current until the protection circuit resets.
If it is desired to program the output voltage down to a
lower value without the need to draw full output current,
the reset time is not important. The reset time can take
from 500msec to 6 seconds depending upon the particular
model, the load, and the starting and the ending voltage
values. For example, the actual output voltage of a 6264B
supply takes only 80msec for its output to go from 20 volts
down to .1% (20 millivolts), but it will be about 800 milli¬
seconds before the circuit resets allowing the full output
current to be supplied to the load. Additional information
concerning this protection circuit.is provided in HP-IB/
Power Supply Guide, HP Part No. 5952-3990.
3-48 Special Option J30. An additional circuit, desig¬
nated special Option J30, is required when CV programming
models 6427B through 6448B and 6466C through 6483C.
The Option J30 circuit is a voltage-to-current converter and
is required because the 59501B is essentially a constant
voltage source. The above supplies utilize current sources in
their programming networks. The programmable 0 - 10V
output of the 59501B is connected to the Option J30 input
terminals (+ and --) on the rear of the supply as shown in
Figure 3-10. One characteristic of the J30 converter is that
if its input is open circuited, the output of the power supply
will rise to about 25% of its rating. With the 59501B con¬
nected, the open circuit condition is prevented because a
protection circuit in the 59501B presents a low impedance
to the J30 input when ac power is removed from the 59501B
(see paragraph 4-13).
3-49 If the Option J30 power supply's front panel
VOLTAGE controls are left connected in the circuit, they
must be set to maximum resistance (fully CW). If they are
rotated COW, the output of the supply will be decreased
for all programming voltage received from the 59501B,. As
indicated on Figure 3-10, the user may disable the front
panel VOLTAGE controls and connect the 59501B's
POWER SUPPLY FULL SCALE ADJUST in their place.
Refer to the applicable power supply's Operating and
Service Manual for additional connection information.
NOTE: The dotted line connections represent jumpers
which must be removed. All other jumpers must be installed.

3-50 CC Programming Connections. Figures 3-14
through 3-20 illustrate the connections required to program
the CC output of the applicable power supplies. The dotted
connections represent jumpers which must be removed on
the supply's rear terminal strip. All other jumpers must be
connected as illustrated. Note that only those power supply
terminals pertinent to CC programming are shown. Complete
terminal strip details are provided in the appropriate power
supply Operating and Service manual. Most of the supplies
are programmed utilizing the connection diagram of Figure
3-14. The specific connections for each supply are tabulated
on the diagram. In all cases (Figures 3-14 through 3-20),
the 59501 B's programming output voltage is substituted for
the supply's internal reference and the 59501 B's POWER
