MC400G Series

Power Factor Controller

The MC400G Series Power Factor Controller offers 18 relay outputs or 8 relay outputs plus 8 thyristor outputs. Through master-slave connection, it can provide up to 32 relay outputs, enabling both control methods to operate simultaneously within the same controller for capacitor switching. This meets user demands for large-capacity reactive power compensation.
