DC OUTPUT CONNECTOR AND SIGNALS
The DC Output Connector is a TYCO MINIPAK HDL Connector TYCO P/N: 1926734-1. Mating pin sequencing shall be 12V_RTN fi rst, 12V second, signals third and PSKILL_L signal
last. PSKILL_L is the last to mate and fi rst to break and is used as a power supply output enable for the 12V rail.

WIRING DIAGRAM
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.
