54mm 1U Front End AC-DC Power Supply Converter
PRODUCT OVERVIEW
The D1U2-W-400-12-HA4C is a 400 watt, power factor corrected front end supply with a 12V main output and a 5V
(15W) standby. It features active current sharing and up to 4 supplies maybe operated in parallel. The supply may be hot
plugged, it recovers from overtemperature faults, and has status LEDs on the front panel in addition to logic and PSMI
status signals. The supply comes in a low profile 1U package and has >8W/cubic inch power density, making it ideal for
delivering reliable, efficient power to servers, workstations, storage systems and other 12V distributed power systems.
