OPERATING MANUAL
1.0 INTRODUCTION
This operating manual should be read through carefully before installing and
operating the TMN/TMP Series hot-swap power systems.
The TMN/TMP Series hot-swap modules and rack form a bulk power front end
with high-power outputs at 24, 28 or 48VDC. See Figure 1. Each TMN module
has a 1000-watt output: 24V at 42A, 28V at 36A or 48V at 21A. Each TMP
module has a 1200-watt output: 24V at 50A, 28V at 43A or 48V at 25A.Three
modules in a rack produce up to 24V at 150A, 28V at 129A or 48V at 75A. Using
the three modules in a 2+1 redundant configuration produces up to 24V at 100A,
28V at 86A or 48V at 50A. The modules have single-wire active load sharing for
automatic paralleling of outputs, and output ORing diodes permit hot-swap
addition or replacement of modules while the system is operating.
The TMN Series operate worldwide with a 85-264VAC input range at 47-63Hz.
The TMP Series operates with a 170-264VAC input range at 47-63Hz. Each
module has input power factor correction and a Class B EMI filter. The output
voltage is tightly regulated. There is a green AC power good LED and green DC
power good LED on the front panel. Each module is self-cooled by an 80mm
internal fan.
The TMN/TMP Series rack has two copper bus bars for the output and a 25-pin
subminiature D connector on the back for the control functions: AC power good,
DC power good, current share, enable, remote sense and remote output adjust-
ment.
The hot-swap modules and racks are safety agency certified and CE marked.

7.0 DESCRIPTION OF OPERATION
7.1 Block Diagram. A diagram of a TMN/TMP Series Module is shown in
Figure 2. The AC input first goes through a Class B EMI filter then to a
full-wave rectifier and high-frequency (45kHz) power factor correction
(PFC) converter. The output of the PFC converter is a regulated DC
voltage at approximately +385V. This voltage is converted down to 24, 28
or 48VDC nominal, depending on the model. This is done by a forward
converter operating at 150 kHz. The output of this converter goes through
a rectifier, filter and ORing diode to the module output. Feedback from
the remote sense terminals back to the forward converter pulse-width
modulator regulates the output voltage and keeps it constant.
7.2 Power Factor Correction. This high-frequency converter circuit, switch-
ing at 45kHz, achieves a power factor of 0.99 by forcing the AC input
current into a sinusoidal waveform, in phase with the input voltage. The
input current is a smooth sine wave of much lower amplitude than the
normal series of high-amplitude, input current pulses that are present in a
unit without power factor correction. The result is lower RMS input cur-
rent for a given output power level.
7.3 Cooling Fan. Another output from the forward converter is rectified,
filtered and used to power the DC ball bearing cooling fan in the module.
7.4 Interface Signals. The module incorporates a number of interface con-
trol and supervisory signals which operate off internal circuits and are
brought to the outside. These include remote enable, which enables or
inhibits the entire rack, remote sensing, remote output adjust and a cur-
rent share connection which permits operating the rack in parallel with
other racks for increased power. Other signals brought out of the rack for
each module are AC good and DC good.

TMN/TMP SERIES
OPERATING MANUAL
10.0 DESCRIPTION OF FEATURES & OPTIONS
DESCRIPTION
The input current is a sine wave in-phase with the input voltage
to give a power factor of 0.99. Input current total harmonic
distortion meets EN61000-3-2.
The AC input range is continuous from 85 to 265VAC (TMN) or
170 to 264VAC (TMP), 47-63Hz, for worldwide operation.
This filter suppresses conducted noise from the module back
onto the AC line. The filter meets FCC20780 part 15J Curve B
and EN55022 Curve B.
When the module is turned on from a cold start, the initial input
current is limited to a peak value of 50 amperes.
For a 48V unit the adjustment range is 45V to 58V. For a 24V
model the adjustment range is 22.5V to 29V. The adjustment is
made from the front panel by means of a 12-turn potentiometer
or from the input to the remote adjust terminal.
This input is used to remotely adjust each module output
voltage. An analog voltage from 0 to +5V controls approxi-
mately 45-58V output for a 48V module or 22.5-29V output for a
24V module. The analog inputs can also be connected together
so that the external control voltage adjusts all the module
outputs simultaneously.
If the output power converter overheats, the TMN/TMP module
will automatically shut down. The DC Good LED also turns off.
After a few minutes the module will cool and automatically start
up again.
The TMN/TMP modules are automatically connected to current
share with each other when they are inserted into the rack. A
single-wire connection provides this. The modules current share
with an accuracy of 10% of their full load output current for total
loads of 50% to 100%. The rack current share pin can be used
to current share with another rack of the same output voltage.
This diode in series with each module output protects the
parallel-connected modules. If the output of one module fails to
a short or to a lower than normal output voltage, the other
modules are not affected. Also when hot-swapping modules,
the diode prevents a glitch in the output voltage while the output
is still rising on the inserted module.

FEATURE / OPTION DESCRIPTION
The output is protected from overvoltage due to fault
conditions in the module. Overvoltage protection is set at
approximately 29V for the 24V version, 34V for the 28V
version and 59V for the 48V version. The result is a latched
shutdown of the module. It is reset by cycling the AC input
off for about 20 seconds and then back on.
The module output can be operated down to zero load while
maintaining output regulation.
Hot swap operation means that the modules can be re-
moved and replaced while the rack is powering the load. If
the rack is operated in an N+1 redundant mode, hot-swap
replacement will not affect the output voltage.
Output current limiting protects the output of each module
from damage due to overload or other short circuit condi-
tion. This protection is continuous, without damage, and
recovery is automatic when the overload is removed.
Current limiting begins at about 105% of rated output
current.
The AC Good indicator is a green LED, showing that input
AC is present and that the PFC converter and internal
control supply are operating. The DC Good indicator is a
green LED showing that the output voltage is present and
within operating range.

13.0 OPERATING INFORMATION
13.1 Input Voltage. The TMN/TMP Series modules operate off worldwide AC
input voltages within the range of 85 to 264 VAC (TMN) or 170-264VAC
(TMP), at 47 to 63 Hz. There is a separate input connection for each
module to a terminal block at the rear of the rack mount. For complete
details see Section 18.2 and Figure 5.
13.2 Output Connection. The 24V, 28V or 48V output is provided on two
copper bus bars. Each bus bar has four 1/4-inch holes. Connection
should be made by means of 1/4-inch diameter bolts. For complete details
see Section 18.3 and Figure 5. Both positive and negative outputs are
floating and isolated from the chassis.
13.3 Output Voltage. The output voltage of each module is factory set to 24,
28 or 48 volts, ±1%. The voltages, however, may be adjusted by means of
the front panel potentiometer or the voltage adjust input pin.
13.4 Output Power. Maximum output current for a TMP module is 50A at 24
VDC, 43A at 28VDC or 25A at 48VDC, giving a maximum output power of
1200 watts. For a TMN module, maximum output power is 1000 watts.
The maximum output power of a module may be drawn at up to 50oC
ambient temperature. Above 50oC the output current must be derated by
2.5%/oC. See Figure 6. The maximum operating temperature is 70oC, at
which the output current must be derated by 50%.
13.5 Output Overload Protection. Each module output is protected from
damage due to overload or other short circuit condition. This protection is
continuous and without damage; recovery is automatic when the overload
or short is removed. The current limit characteristic is a constant current
above 40V, 23V or 20V (depending on model). Current limiting takes
place at approximately 105% of the rated output current.

OPERATING MANUAL
13.6 Remote Sensing. Remote sensing connections are made to pins 11
(+Sense) and 23 (-Sense) of the rack J1 connector. Remote sensing is
used to regulate the output voltage at the point of load by compensating
for the voltage drop in the wires to the load. The +Sense lead must be
connected to the + side of the load and the -Sense to the - side of the
load. The sense leads should be a color-coded, twisted pair of AWG no.
22 or 24 copper wire. See Figure 7.
Remote sensing can compensate for a total voltage drop of 0.5V, or 0.25V
per load wire. The sense leads should not exceed 10 feet (3 meters) in
length. If remote sensing is not required, the sense leads may be left
open; there is an internal 10-ohm resistor connected from each output to
its remote sense lead. Be careful not to reverse the sense lead con-
nections, as this will blow the 10-ohm resistors.
13.7 Control & Supervisory Signals. All control and supervisory signals are
accessible at J1, a 25-pin subminiature D connector on the back of the
rack. See Section 17 for a complete description of these input and output
signals.
13.8 Alarm Signals. Among the control and supervisory signals are two logic
alarms for each module: AC Good and DC Good. They are TTL-compat-
ible signals referenced to Signal Common, J1 Pin 22 on the rack. AC
Good: A logic HI or open indicates that there is no AC input and the PFC
converter stage has failed. DC Good: A logic HI or open indicates a DC
output failure.
14.0 PARALLEL OPERATION
The TMN/TMP modules in the rack are all connected in the parallel, current
sharing mode by means of a single-wire current share connection among them.
A rack can be operated in either an N+1 redundant mode or a non-redundant
mode.
14.1 Redundant Operation. From Table 14-1, the 19-inch rack mount can be
operated in a 2+1 redundant mode. This means, for example, that the full
load current must be carried by two modules. While operating normally
the current is shared approximately equally among the three modules. If
one module fails, however, the output current is then maintained by the
two operating modules. The failed unit can be replaced without affecting
the output current to the load. N+1 redundancy with quick replacement of

15
TMN/TMP SERIES
OPERATING MANUAL
a failed module results in virtually infinite MTBF.
Table 14-1 Redundant and Non-Redundant Operation
14.2 Non-Redundant Operation. Higher output current can be achieved by
operating the rack in a non-redundant mode as seen in Table 14-1. How-
ever, in this case if a module fails, the load will lose power since only part
of the required current can be supplied by the remaining modules, and
they will go into current limit. The failed module, however, can be quickly
replaced to restore the load current.
14.3 Multiple Parallel Rack Operation. Multiple racks can also be operated
in parallel by interconnecting their current share terminals (J1 Pin 10).
The total power can be expanded by several times. In this case N+1
redundant operation is achieved by reserving one module of the total for
redundancy. For example, if two full 19-inch racks are employed with a
total of six modules, then 5+1 redundancy is achieved and the full load
must be able to be carried by the output of five modules. In such applica-
tions each set of remote sense wires must be separately connected to the
point of load. See Figure 8 for a simplified illustration of two TMN/TMP
racks connected in parallel.
15.0 RACK CONTROL & SUPERVISORY SIGNAL CONNECTIONS
15.1 Connections for control and supervisory signals are made at the rack rear
to connector J1, a standard 25-pin subminiature D connector (Positronics

DESCRIPTION

+ Sense
- Sense
This is an analog control signal made up of the current share
signals of all modules connected together. This pin is used to
connect to Pin 10 of another identical rack to share output
currents. Output currents between racks are shared within an
accuracy of 10% of full load current over a 50% to 100% load
range. This signal is referenced to -Sense, Pin 23.
These remote sense leads should be connected as a twisted pair
to the respective + and - load points to provide regulation at the
point of load. Removal of the sense leads transfers regulation
control to the output terminals of the rack via internal 10-ohm
senseresistors.
