D1U3CS-W-1200-12-HxxC Series
81mm 1U Front End AC-DC Power Supply Converter
www.murata-ps.com
PRODUCT OVERVIEW
The D1U3CS-W-1200-12-HxxC series are 80 PLUS Gold efficiency 1200 watt, power factor corrected front end supplies
with a 12V main output and a 5V or 3.3V (20W) standby. They have active current sharing and up to 8 supplies may be
operated in parallel. The supplies may be hot plugged, they recover from overtemperature faults, and have status LEDs
on their front panel in addition to logic and PMBus™ status signals. Their low profile 1U package and >21W/cubic inch
power density make them ideal for delivering reliable, efficient power to servers, workstations, storage systems and
other 12V distributed power systems.
