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.

TMN/TMP SERIES

OPERATING MANUAL

OPERA TING MANUAL

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 adjust­ment.

The hot-swap modules and racks are safety agency certified and CE marked.

4.0 SAFETY W ARNINGS

4.1 These hot-swap modules and racks have hazardous external and internal

voltages. They should be handled, tested and installed only by qualified
technical persons who are trained in the use of power systems and are
well aware of the hazards involved.

4.2 The input terminals are at hazardous voltage potentials. Do not touch this
area when power is applied.

4.3 When operating this power system, the frame ground terminal must be
connected to safety ground by means of a three-wire AC power line to
minimize electrical shock hazard and to ensure low EMI (electromagnetic
interference).

4.4 The internal voltages are at hazardous potentials. The module covers
should not be removed. There are no user-serviceable components in
these units. Removing the covers of the modules will void the warranty.

5.0 WARRANTY

All products of UNIPOWER Corporation are warranted for two (2) years from date of shipment
against defects in material and workmanship. This warranty does not extend to products which
have been opened, altered or repaired by persons other than persons authorized by the manu­facturer or to products which become defective due to acts of God, negligence or the failure of
customer to fully follow instructions with respect to installation, application or maintenance. This
warranty is extended directly by the manufacturer to the buyer and is the sole warranty appli­cable. EXCEPT FOR THE FOREGOING EXPRESS WARRANTY, THE MANUFACTURER
MAKES NO WARRANTY, EXPRESS OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. As the
sole and exclusive remedy under this warranty, the manufacturer, at its option, may repair or
replace the non-conforming product or issue credit, provided the manufacturer’s inspection
establishes the existence of a defect. To exercise this remedy, the buyer must contact the
manufacturer’s Customer Service Department to obtain a Return Material Authorization number
and shipping instructions. Products returned without prior authorization will be returned to buyer.
All products returned for repair must be shipped freight prepaid to UNIPOWER. If the buyer fails
to fully comply with the foregoing, the buyer agrees that no other remedy (including, but not
limited to, incidental or consequential damages for lost profits, lost sales, injury to person or

property or any other incidental or consequential losses) shall be available to the buyer.

OPERATING MANUAL

6.0 UNP ACKING AND INSPECTION

6.1 This TMN/TMP Series Power System was carefully tested, inspected and

packaged for shipment from our factory. Upon receipt of the unit it should
be carefully unpacked and inspected for any damage in shipment.

6.2 If there is evidence of damage, do not attempt to test the unit. The freight
carrier should be notified immediately and a claim for the cost of the
power system should be filed with the carrier for direct reimbursement.
Be sure to include the model and serial number of the damaged unit in all
correspondence with the freight carrier. Also save the shipping carton
and packing material as evidence of damage for the freight carrier’s

inspection.

6.3 UNIPOWER Corporation will cooperate fully in case of any shipping
damage investigation.

6.4 Always save the packing materials for later use in shipping the unit.
Never ship the rectifier system without proper packing.

7.0 DESCRIPTION OF OPERA TION

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.

TMN/TMP SERIES

OPERATING MANUAL

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 cur­rent 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 con­trol 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 cur­rent 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.
