D1U3CS-D-850-12-HxxC Series
DC/DC Front End Power Supply
PRODUCT OVERVIEW
The D1U3CS-D-850-12-HxxC series are highly efficient 850 watt, DC input 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 logic and PMBus status signals. Their
low profile 1U package and >15W/cubic inch power density make them ideal for delivering reliable, efficient power for
telecom and other 12V distributed power systems that include servers, workstations and storage systems.
