D1U3CS-D-850-12-HxxC Series www.murata-ps.com 81mm 1U Front End DC-DC Power Supply Converter PRODUCT OVERVIEW The D1U3CS-D-850-12-HxxC series are highly ef cient 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 pro le 1U package and >15W/cubic inch power density make them ideal for delivering reliable, ef cient power for telecom and other 12V distributed power systems that include servers, workstations and storage systems.
