WIRING DIAGRAM FOR OUTPUT
CURRENT SHARING NOTES
12V Output: Current sharing is achieved using the active current share method. (See wiring diagram for connection details.)
The total combined load must be below 1600W at startup. Current sharing can be achieved with or without remote sense connected to the common load.
V_SB outputs can be tied together for redundancy but total combined output power must not exceed 20W. The V_SB output has internal ORing MOSFET for
additional redundancy / internal short protection.
The current share pin B1 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 6 units can be paralleled together. Please consult your Murata sales representative if operation with more than six units in parallel is needed.
