TPCMQ48 & TPCMQ24 SERIES DC/DC CONVERTERS
1.0 INTRODUCTION
This operating manual should be read through carefully before installing and
operating the TPCMQ48 and TPCMQ24 DC/DC converter systems.
Unipower’s 1U high DC/DC converter systems convert a 48VDC nominal
input to 12 and 13.6VDC at 1800 and 1950 watts, respectively, or to 24 and
27.2VDC at 2,100 watts; or a 24VDC nominal input to 48 or 54.4VDC at
3,000 watts. The converter system consists of three DC/DC converter modules
in a compatible 19-inch rack/shelf. See Figure 1. The input is a wide
range 40 to 60 or 20 to 30VDC, and the output has a -25 to +10% adjustment
range. In 2+1 redundant operation the output is 1,400 watts for the
TPCMQ48 or 2,000 watts for the TPCMQ24. In this case a converter module
can be hot-swapped without affecting the output. The output voltage can be
controlled by a remote analog input in the range 0 to +5V.
TPCMQ DC/DC CONVERTER SERIES
OPERATING MANUAL
OPERATING MANUAL
AND RACK/SHELF
Each TPCMQ48 converter module produces 12, 13.6, 24 or 27.2VDC at 700
watts, and each TPCMQ24 module produces 48 or 54.4VDC at 1,000 watts.
The modules, which are connected in parallel in the rack/shelf, have automatic
load sharing and ORing diodes so they can be added or replaced while the
system is operating. The modules are up to 89% effi cient and have up to 12.5
watts per cubic inch power density.
A 25-pin interface subminiature D connector on the back of the rack/shelf provides control and monitoring inputs and outputs. An inhibit input turns the entire
rack/shelf output off or on. Remote sensing connections provide precise regulation at the point of load. Other control signals are input power fail and output
power good logic signals, and analog voltage remote adjust inputs- all for each
individual converter module.
Front-panel green LEDs indicate input power good and output power good for
each converter module. The converter modules and rack/shelf are safety agency certifi ed and CE marked.

4.0 SAFETY WARNINGS
3.1 These converter modules and shelf have hazardous external and
internal voltages. They should be handled, tested and installed only
by qualifi ed 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.

OPERATING MANUAL
4.3 When operating this converter system, the frame ground terminal must be
connected to safety ground to minimize electrical shock hazard.
4.4 The internal voltages are at hazardous potentials. The converter 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.
