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 efciency 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 prole 1U package and 21.4W/cubic inch power density make them ideal for delivering reliable, efcient power to networking equipment, workstations, storage systems and other 12V distributed power architectures.
