54mm 1U Front End HVDC Power Supply Converter
PRODUCT OVERVIEW
The D1U54-HD-1200-12-HA4C is a high efficiency 1200 watt, HVDC input front end supply with a 12V
main output and a 5V (3A) standby. It has active current sharing and up to 8 supplies may be operated in
parallel. The supplies may be hot plugged, recovers from overtemperature faults, and has status LEDs on
the front panel in addition to logic and PMBus™ status signals. Its low profile 1U package and >28W/cubic
inch power density make it ideal for delivering reliable, efficient power to datacenters, servers,
workstations, storage systems, and other 12V distributed power systems.
