2.1 Input Voltage Range
¡Input voltage range of the power supplies is from AC85V to
AC264V or DC (please see SPECIFICATIONS for details).
The units comply with safety agency approval only when input
voltage is provided by AC.
¡If input value doesn’t fall within above range, a unit may not oper-
ate in accordance with specications and/or start hunting or fail.
If you need to apply a square waveform input voltage, which is
commonly used in UPS and inverters, please contact us.
¿ PBA10F, PBA15F, PBW15F, PBA30F and
PBW30F
¡A power factor improvement circuit (active lter) is not built-in. If
you use multiple units for a single system, standards for input har-
monic current may not be satised. Please contact us for details.
¿ PBA10F, PBA15F, PBW15F, PBA30F,
PBW30F, PBA50F, PBW50F, PBA75F,
PBA100F and PBA150F
¡Operation stop voltage is set at a lower value than that of a stan-
dard version (derating is needed).

* Please avoid using continuously for more than 1 second
under above conditions. Doing so may cause a failure.
¿
PBA300F, PBA600F, PBA1000F and PBA1500F
¡You can use a unit with an input voltage lower than AC85V and
DC120V by option (please see 7. Options). If you do so, load de-
rating is necessary. Please contact us for details.
2.2 Inrush Current Limiting
¡An inrush current limiting circuit is built-in.
¡If you need to use a switch on the input side, please select one
that can withstand an input inrush current.
¿ PBA10F
¡Resistance for load factor is used for inrush current limiting.
¿ PBA15F, PBW15F, PBA30F, PBW30F,
PBA50F,PBW50F, PBA75F, PBA100F and
PBA150F
2 Functions ¡Thermistor is used in the inrush current limiting circuit. When you
turn the power ON/OFF repeatedly within a short period of time,
please have enough intervals so that a power supply cools down
before being turned on.
¿
PBA300F, PBA600F, PBA1000F and PBA1500F
¡Thyristor technique is used in the inrush current limiting circuit.
When you turn the power ON/OFF repeatedly within a short period
of time, please have enough intervals so that the inrush current
limiting circuit becomes operative.
¡When the switch of the input is turned on, the primary inrush cur-
rent and secondary inrush current will be generated because the
thyristor technique is used for the inrush current limiting circuit.
2.3 Overcurrent Protection
¡An overcurrent protection circuit is built-in and activated at 105%
of the rated current or 101% of the peak current. A unit automati-
cally recovers when a fault condition is removed.
Please do not use a unit in short circuit and/or under an overcur-
rent condition.
¡Intermittent Operation Mode
When the overcurrent protection circuit is activated and the output
voltage drops to a certain extent, the output becomes intermittent
so that the average current will also decrease.
¿ PBA1000F and PBA1500F
¡Output Voltage Shutdown
If the overcurrent protection circuit operates continuously for 5
seconds, the output voltage will shut down. To recover the output
voltage, remove a condition that is causing an overcurrent, shut
down the input voltage, wait more than 3 minutes and turn on the
AC input again.
2.4 Overvoltage Protection
¡An overvoltage protection circuit is built-in. If the overvoltage pro-
tection circuit is activated, shut down the input voltage, wait more
than 3 minutes and turn on the AC input again to recover the out-
put voltage. Recovery time varies depending on such factors as
input voltage value at the time of the operation.
¿ PBA600F, PBA1000F and PBA1500F
¡In addition to a standard overvoltage protection circuit, an over-
voltage protection circuit to follow to output voltage is built-in. If an
output voltage exceeds a pre-set value, the overvoltage protection
circuit to follow to output voltage is activated and shut down the
output voltage.
*The Overvoltage protection circuit to follow to output voltage is
optional for PBA300F.
Note :
¡Please avoid applying a voltage exceeding the rated voltage to an
output terminal. Doing so may cause a power supply to malfunc-
tion or fail. If you cannot avoid doing so, for example, if you need
to operate a motor, etc., please install an external diode on the
output terminal to protect the unit.
Unit type Instruction Manual
A-34
PB

PB

¡In PBA600F, 1000F and PBA1500F series, the overvoltage protec-
tion circuit is a tracking method in which the detection point is set
depending on output voltage setting. However, even if a sensing
line makes open or external voltage is applied to output terminal
in order to activate the function at receiving inspection, the track-
ing function does not work, so the function is activated with higher
value in a catalog.
Therefore, do not perform the function test to avoid the any trou-
ble.
2.5 Thermal Protection
¿
PBA300F, PBA600F, PBA1000F and PBA1500F
¡A thermal protection circuit is built-in.
The thermal protection circuit may be activated under following
conditions and shut down the output.
1
When a current and a temperature continue to exceed the val-
ues determined by the derating curve.
2
When a fan stops or air ow is blocked from the fan and weak-
ens.
If the thermal protection circuit is activated, shut off the input volt-
age and eliminate all the overheating conditions. To recover the
output voltage, have enough time to cool down the unit before
turning on the input voltage again.
2.6 Output Voltage Adjustment
¡To increase an output voltage, turn a built-in potentiometer clock-
wise. To decrease the output voltage, turn it counterclockwise.
¿ PBA10F, PBA15F, PBW15F, PBA30F,
PBW30F, PBA50F, PBW50F, PBA75F,
PBA100F and PBA150F
¡We are offering an Option -V, which doesn’t have a built-in poten-
tiometer but instead enables you to adjust the output voltage by
using an external potentiometer (please see 7 Options).
¿
PBA300F, PBA600F, PBA1000F and PBA1500F
¡The power supplies have an external output voltage control func-
tion. The output voltage can be adjusted within a 110% range
from almost 0V by changing the voltage between the terminal
TRM and the terminal -S on CN1. You can decrease the voltage
by drawing a current from the TRM terminal.
You can calculate the output voltage in this case from formula 1
below.
Please note that the formula 1 gives you only an estimate.
Please contact us if you need accurate numbers.
Output voltage = Xrated output voltage---1
Please do not apply an external voltage of -0.7V or less or 3.0V
or more.
There is more than one method to adjust the output voltage, in-
cluding the methods to use external resistors and external power
supplies. Since each method has different characteristic, please
contact us for details.
¡If the terminal TRM opens while the external output voltage control
function is in use, a unit generates the rated voltage.
If the terminal VB and the terminal -S are connected and the ter-
minal TRM opens as shown in Fig.2.1, the unit stops generating
the output voltage.
¡You can change the control voltage of TRM from 0 - 2.75V to 0 -
5.5V by serially connecting 1.73W to the TRM terminal as shown
in Fig.2.2.
¡If the output voltage decreases to almost 0V, a fan may stop, out-
put ripple may become large and PG signals may turn to ”High.”
2.7 Remote ON/OFF
¿ PBA10F, PBA15F, PBW15F, PBA30F and
PBW30F
¡These models do not have a remote ON/OFF function.
¿ PBA50F, PBW50F, PBA75F, PBA100F and
PBA150F
¡Option -R is available to provide a remote ON/OFF function.
Please see ”7. Options” for details.
¿ PBA300F, PBA600F, PBA1000F and PBA1500F
¡These models have a remote ON/OFF function.
You can operate the remote ON/OFF function by sending signals
to CN1. Please see Table 2.1 for specications and Fig.2.3 for
connecting examples.
¡Remote ON/OFF circuits (RC2 and RCG) are isolated from input,
output, FG and AUX.
¡Please note the followings when using the remote ON/OFF func-
tion.
1The output stops when a current ows to RC.
2The current own to RC is a 5mA type (maximum 12mA).

2.8 Remote Sensing
¿ PBA10F, PBA15F, PBW15F, PBA30F,
PBW30F, PBA50F, PBW50F and PBA75F
¡These models do not have a remote sensing function.
¿ PBA100F and PBA150F
¡Option -K is available (for -3R3 and -5) to support a remote sens-
ing function. Please see ”7. Options” for details.
¿
PBA300F, PBA600F, PBA1000F and PBA1500F
¡These models have a built-in remote sensing function.
If you do not use the remote sensing function, you can short out
between +S and +M and between -S and -M on CN1.
When the power supplies are shipped from a factory, they come
with a dedicated harness (H-SN-19) being mounted on CN1. If
you do not use the remote sensing function, you can use the
power supplies as they are.
¡Please see Fig.2.4 if you do not use the remote sensing function.
Please see Fig.2.5 if you use the remote sensing function.
¡When you use the remote sensing function, please wire from
+S and -S on CN1. Harnesses are available for your purchase.
Please contact us for details.
When you use the remote sensing, please note the followings.
1Wire carefully. When a connection of a load line becomes loose
(due to such factors as loose screw), the load current ows to
the sensing line and internal circuits of the power supply may be
damaged.
2Use a sufciently thick wire to connect between the power sup-
ply and the load and keep the line drop at 0.3V or below.
3If the sensing line is long, connect C1 and R1.
4Use a twisted pair wire or a shielded wire as the sensing line.
5Do not draw the output current from +M, -M, +S or -S.
6When the remote sensing function is used, the output voltage
of the power supply may show an oscillating waveform or the
output voltage may dramatically uctuate because of an imped-
ance of wiring and load conditions.
Please check and evaluate carefully before using the remote
sensing function.
If the output voltage becomes unstable, we suggest you to try
the followings.
-
Remove the remote sensing line on the minus side and short
out between -S and -M.
-Connect C1, R1 and R2.
Please contact us for details.
3If the output voltage is turned off through the remote ON/OFF
circuit, the built-in fan stops.
In the case of PBA300F, the fan slows down when the output
voltage is turned off through the remote ON/OFF circuit.
4If the output voltage is turned off through the remote ON/OFF
circuit, PG signals turn to ”High.”
5Description in this section is based on the assumption that you
will use one unit alone. If you are planning to use the units
in parallel operation or use multiple units for a single system,
please check necessary voltage and current values.
6If voltage or current of a value not listed in Table 2.1 is applied
between RC2 and RCG, the output voltage may not be gener-
ated normally.

¡You can use a power supply in series operation. The output cur-
rent in series operation should be lower than the rated current of a
power supply with the lowest rated current among power supplies
that are serially connected. Please make sure that no current ex-
ceeding the rated current ows into a power supply.

2.9 Alarms
¿
PBA300F, PBA600F, PBA1000F and PBA1500F
¡Alarms (PG signal) are generated from CN3. Please see Table
2.2 for the functions of the alarms. The objective of the PG sig-
nals is to detect whether or not a certain function of a power sup-
ply is working. It takes several seconds to generate the alarm
signals and the timing when the alarm signals are generated is in-
consistent. Please check if the objective of the alarm is achieved.
¡Please note the followings when you use the alarms (PG signal).
1
The time it takes until the PG signals turn ”High” vary depending
on models and conditions.
PBA300F and PBA600F ….. less than 1 second
PBA1000F and PBA1500F ….. less than 10 second
2
If the output voltage is turned off through a remote ON/OFF cir-
cuit, the PG signals turn ”High”.
3
The PG signal may turn ”High”, if the output current becomes
10% or below of the rated current in parallel operation (in this
case, the fan also stops).
4
If the output voltage is decreased to almost 0V or decreased
rapidly through an external adjustment mechanism when load is
light, The PG signal may turn ”High”.
¡The PG signal (Alarm) circuit is isolated from input, output, FG,
RC and AUX.

*Synchronous rectication method is employed for these products
and therefore you cannot use them in parallel operation without
OR diode.
¡Even a slight difference in output voltage can affect the balance
between the values of I1 and I2.
Please ne-tune the output voltage so that a current from each
power supply does not exceed its rated current and a balance
among output current values is kept.

¿
PBA300F, PAB600F, PBA1000F and PBA1500F
¡You can use the power supplies in parallel operation by connect-
ing units as shown in Fig.4.3.
Please parallelly connect ±S, VB and CB of each power supply in
parallel operation and connect ±S and ±M on CN1 of the master
power supply.
When the power supplies are shipped from a factory, they come
with a dedicated harness (H-SN-19) being mounted on CN1.
Please remove the dedicated harness (H-SN-19), which is mount-
ed on CN1 of the slave power supply, and use an optional har-
ness, H-PA-3, to connect ±S, VB and CB parallelly.
Differences in the output current values among the power supplies
in parallel connection are 10% at most. Please make sure that
the sum of the output current values does not exceed a value ob-
tained from the right side of the following equation.
(Output current in parallel operation)
= (Rated current per unit) X (Number of units) X0.9
¡When the number of units in parallel operation increases, the in-
put current also increases. Please design input circuitry (including
circuit pattern, wiring and current capacity for equipment) carefully.
¡Please make sure that the wiring impedance of a load from each
power supply becomes even. Otherwise, the output current bal-
ance circuit may become inoperative.
¡The maximum number of units you can use in parallel operation is
5.
4.2 Parallel Operation/Master-slave Operation
¿ PBA10F, PBA15F, PBW15F, PBA30F,
PBW30F, PBA50F, PBW50F, PBA75F,
PBA100F and PBA150F
¡You can use the power supplies in parallel operation by connect-
ing units as shown below.
¡You can adjust the output voltage in parallel operation by adjusting
a potentiometer of just one power supply.
To do so, select one power supply as the master unit and turn the
potentiometers of the other (slave) power supplies clockwise to
the end.
Once you have done this, you can adjust the output voltage by
turning the potentiometer of the master unit.
¡If you use the remote sensing function in parallel operation, con-
nect parallelly +S and -S of slave power supplies must be con-
nected to master and connect the sensing wire from the master
unit to the load.
¡You cannot parallelly operate power supplies with different output
voltage or electrical power.
¡If an output stops (through the remote ON/OFF circuit or due to
an input shutoff or failure) in parallel operation, the LED of the
stopped unit lights off.
¡When the load becomes 10% or less of the rated current, the PG
signals may turn ”High” and the fan may stop. In this case, the
LED also lights off.
4.3 N+1 Parallel Redundancy Operation
¿
PBA300F, PAB600F, PBA1000F and PBA1500F
¡You can have N+1 redundancy operation for improved system reli-
ability.
¡If you add one extra power supply in parallel operation, even if
one of the power supplies in your system fails, the remaining non-
failed power supplies continue to sustain the system. If one of the
power supplies stops operating, the output voltage may change
about 5%.
¡If you have any questions about series, parallel and N+1 redun-
dancy operations, please contact us.

5.1 Installation
¡Do not insert a screw more than 6mm from the outside of a power
supply to keep enough insulation distance between the screw and
internal components.
5 Assembling and
Installation
¿ PBA10F, PBA15F, PBW15F, PBA30F,
PBW30F, PBA50F, PBW50F, PBA75F,
PBA100F and PBA150F
¡If you use two or more power supplies side by side, please keep
a sufcient distance between them to allow enough air ventilation.
Ambient temperature around each power supply should not ex-
ceed the temperature range shown in the derating curve.
¿
PBA300F, PAB600F, PBA1000F and PBA1500F
¡The power supplies have a built-in forced cooling fan. Do not
block ventilation at the suction side (terminal block side) and its
opposite side (fan installation side).
If you need to secure a power supply by screws, securely x it,
taking into consideration of its weight. You can install it in any di-
rection.
¡If you use a power supply in a dusty environment, it can give a
cause for a failure. Please consider taking such countermeasures
as installing an air lter near the suction area of the system to pre-
vent a failure.

6.3 Isolation
¡When you run a Hi-Pot test as receiving inspection, gradually in-
crease the voltage to start. When you shut down, decrease the
voltage gradually by using a dial. Please avoid a Hi-Pot tester
with a timer because, when the timer is turned ON or OFF, it may
generate a voltage a few times higher than the applied voltage.
¡When you test a unit for isolation between the input and output or
between the output and the terminal FG, short-circuit between the
output and the terminals RCG, PGG and AUXG.
6.4 Auxiliary Power (AUX)
¿
PBA300F, PBA600F, PBA1000F and PBA1500F
¡The power supplies can generate an auxiliary power (AUX: 12V
0.1A) from CN3 to provide for remote ON/OFF and attached cir-
cuits.
¡AUX circuit is isolated from other (input, output, FG, RC and PG)
circuits.
¡Please do not draw a current of 0.1A or higher from the auxil-
iary power because doing so could damage the internal circuits or
cause malfunction.
When you connect a DC-DC converter, a current a few times
higher than normal current may ow at start-up. Please check the
current.
6.5 External Component (Noise Filter)
¿ PBA1500F
¡You can have the power supplies comply with FCC Part 15 class
B and EN55022-B by connecting an external noise lter.
Examples of Constant Values of the External Noise Filter
L 1 : 0.45mH L 2 : 0.45mH
C1 : 0.1 F C2 : 0.1 F C3 : 0.1 F
C4 : 4700pF C5 : 4700pF
R1 : 2MW R2 : 2MW
6 Others
6.1 Output Current Monitor
¿
PBA300F, PBA600F, PBA1000F and PBA1500F
¡You can monitor an output current by measuring a voltage be-
tween the terminal CB and the terminal -S on either CN1 or CN2.
¡Fig.6.1 shows the relationship between the voltage of the terminal
CB and the output current.
Fig.6.1 shows a typical characteristic of PBA1500F-5. Please
contact us for the characteristics of the other models.
The output current shown in Fig.6.1 should be used only as a
guide.
¡Please note the followings when measuring the voltage of the ter-
minal CB.
-Wire carefully to avoid malfunction caused by noise.
-Use a measuring instrument whose input impedance is 500W
or more.
-Do not short-circuit between CB terminal and -S terminal. Do-
ing so could cause a failure.
6.2 External Capacity
¿ PBA10F, PBA15F, PBW15F, PBA30F and
PBW30F
¡When a capacitor with large capacity is connected to the load
side, a power supply may stop or start hunting. Please contact us
for details.
