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 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.

(See wiring diagram for connection details.) Current sharing can be achieved with or without remote sense connected to the common load. +VSB outputs can be tied together for redundancy but total combined output power must not exceed 20W. The +VSB output has internal ORing MOSFET for additional redundancy / internal short protection. The current share pin B3 is a connection between the two units. It is input and/or output as the voltage on the line controls the current share. A power supply will respond to a change in this voltage but a power supply can also change the voltage depending on the load drawn from it. On a single unit this would read 8V at 100% load. For two units sharing load then this should read 4V for perfect current sharing. Up to 8 units can be paralleled together. Please consult your Murata sales representative if operation with more than 8 units in parallel is needed. www.murata-ps.com/support D1U3CS-D-850-12-HxxC.B01 Page 4 of 5 D1U3CS-D-850-12-HxxC Series 81mm 1U Front End DC-DC Power Supply Converter MECHANICAL DIMENSIONS 22.80 ±0.60 0.898 ±0.024 275.50 ±0.30 10.846 ±0.012 [1] 7.00 0.275 279.40 ±0.50 11.000 ±0.020 83.80 ±0.30 3.299 ±0.012 7.05 ±0.25 0.277 ±0.010 [1] 39.90 ±0.50 1.571 ±0.020 16.20 ±0.60 0.638 ±0.024 81.30 ±0.50 3.201 ±0.020 31.00 1.220 Airflow Back to Front 15.51 ±0.25 0.610 ±0.010 [1] Airflow Front to Back NOTE [1] CRITICAL TO FUNCTION.
