54mm 1U Front End AC-DC Power Supply Converter
WIRING DIAGRAM
-
Dotted lines show optional remote sense connections.
Optional remote sense lines can be attached to a load that is a distance
away from the power supply to improve regulation at the load.

CURRENT SHARING NOTES
12V Output: Current sharing is achieved using the active current share method. (See wiring diagram section for connection details.) The total combined load must be below
400W at startup. Startup of parallel power supplies is not internally synchronized. It is recommended that the paralleled power supplies be turned on at the same time (with their
PSON_L signals). Current sharing can be achieved with or without remote sense connected to the common load.
5VSB Output: 5VSB outputs can be tied together for redundancy but total combined output power must not exceed 15W. The 5VSB output has internal ORing MOSFET for
additional redundancy / internal short protection.
Up to four units can be paralleled together. Outputs of AC input units (D1U2-W-400) and DC input units (D1U2-D-400) can be paralleled together. Please consult your Murata sales
representative if operation with more than four units in parallel is needed.
