The Active Interface Module essentially comprises a water-cooled filter reactor and a water-cooled filter module. The filter module contains a Clean Power Filter with basic RI suppression, the pre-charging circuit for the Active Line Module, the line voltage sensing circuit and monitoring sensors.

A bypass contactor is provided separately. Active Interface Modules are used in conjunction with Active Line Modules.

The water-cooled Active Interface Modules are specifically designed for the operation of shared cooling circuits for the plant, motor, and converter.
