WIRING DIAGRAM FOR OUTPUT
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
Main 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 the rated standby power. The +VSB output has internal ORing MOSFET for
additional redundancy / internal short protection.
The current share pin B5 (or D4 for alternate pin out model) is a connection between the 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.
