D1U54P-W-450-12-HxxC Series
54mm 1U Front End AC-DC
Power Supply Converter
PRODUCT OVERVIEW
The D1U54P-W-450-12-HAxC series power modules are very high efficiency, 450 watt power factor corrected front end
supplies, with a 12Vdc main output and standby output. An active (digital) current share characteristic is provided to
allow units to operate in parallel and share load current. 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 14.8W/cubic inch power density make them ideal for delivering reliable,
efficient power to networking equipment, workstations, storage systems and other 12Vdc distributed power
architectures.
