Comsys ADF PPM300

The ADF PPM300 inverter module is one of the key components of the ADF System Integration Program. Designed for easy integration into electrical cabinets and motor control centres, this component enables you to build your own active harmonic filter or low harmonic solution.

The ADF “building blocks” can be used to build harmonic compensation solutions, from small to large. From a single PPM system with a single control unit, up to a 90-unit PPM system with 15 control units.

Building on a history of successful installations, the ADF PPM300 tolerates high levels of frequency disturbances and continues to compensate reliably in applications where passive filters are likely to break down.

The robustness of the ADF PPM300 is one of the reasons the ADF product range ideal in very demanding applications, such as island mode grids, weak grids with generators, and marine applications.

Each ADF PPM300 module is engineered to maximize performance in any application.
Each module includes the following features:


Modular building capability

Able to accommodate many different sizes of compensation equipment

Compact design, ideal for small spaces

Individual harmonic control: Open Loop, Closed Loop, Sensorless Control

Fixed switching frequency

Available with air-cooling or liquid-cooling

Available as UL/cUL recognized components
