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 2 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 two units in parallel is needed.
