OPERATING MANUAL
TPCMQ48 SERIES
48VDC INPUT DC/DC CONVERTERS
1.0 INTRODUCTION
This Operating Manual should be read through carefully before installing and operating the TPCMQ48
Series DC/DC converters.
TPCMQ48 is a family of high density hot-swappable, modular DC/DC converters producing up
to 1000 watts output power from a nominal 48VDC source. There are 6 standard models with
different output voltages and power levels. The modules are ultra-compact with power density up
to 12.5 watts per cubic inch. The modules have automatic load sharing and active output ORing
circuit so they can be hot-swapped while the system is operating. When using the optional I²C serial
communications interface, status and control data can be passed between the module and a host
system or power management unit.
Front panel mounted LEDs indicate input and output condition and a +5Vstandby output is also
included. Operating temperature range is -20°C to +70°C.
TPCMQ48 modules can be fully integrated into an OEM host system or alternatively installed into
a matching 1U high 19” rack-mount power shelf. Multiple power shelves may be connected in
parallel for increased system capacity.
Figure 1 below shows a TPCMQ48 module and three modules installed into a power shelves.
