Connecting method of Buffer module ZBM-AC (Option “/BM”)
By connecting our ZBM-AC to CN2, the Hold up time of ZWS300RC can be extended.
Derating the output power of ZWS300RC by 10W per ZBM-AC connection.
The ZBM-AC that can be connected to ZWS300RC is as follows.
When using multiple ZBM-AC units, the maximum number of /S option is one unit.
It is necessary to use harness with withstand voltage of 400V or higher and equivalent to AWG16.
Please be careful about insulation of harness, because CN2 is on the primary side. An optional harness (sold
separately) for connection is available.
For details on how to use ZBM-AC and precautions, refer to the ZBM-AC instruction manual.
