D1U3CS-W-1200-12-HxxC Series
81mm 1U Front End AC-DC Power Supply Converter
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.

CURRENT SHARING NOTES
12V Output: Current sharing is achieved using the active current share method. (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.
