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 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.
