D1U54-D-650-12-HBxC Series
54mm 1U Front End DC-DC Power Supply Converter
PRODUCT OVERVIEW
The D1U54-D-650-12-HBxC products are very high efficiency DC input 650 watt front end supplies provided with a
12V main and a 12V Standby output. An active (analogue) current share characteristic is provided to allow units to be
operated in parallel. The power supply may be hot plugged; recovers from overtemperature faults, and has status
LEDs on the front panel in addition to hardware signal logic and PMBus™ status signals. The low profile 1U package
and 21.4W/cubic inch power density make them ideal for delivering reliable, efficient power to networking
equipment, workstations, storage systems and other 12V distributed power architectures.
