Series Headline 81mm 1U Front End AC-DC Power Supply Converter
Series Description The D1U3CS-W-850-12-HxxC series are 80 PLUS Gold efficiency 850 watt, power factor corrected front end supplies with a 12V main output and a 3.3V (20W) standby. They have active current sharing and up to 4 supplies may be operated in parallel. The supplies may be hot plugged, they recover from overtemperature faults, and have logic and PMBus status signals. Their low profile 1U package and >15W/cubic inch power density make them ideal for delivering reliable, efficient power to servers, workstations, storage systems and other 12V distributed power systems.
