4-7 Series Operation

For this converter series, it is possible to operate models of the same type in series.

The maximum number of converters which can be operated in series is 2.

When using series operation, connect the +Vin terminal , -Vin terminal ,PO terminal and ALM terminal of each converter to

the same terminal of the other.
