ABB Active Harmonic Filters

ABB Active Harmonic Filters


ABB PQF active filters can be applied to small, medium or large _x000D_ applications and are suitable for both industrial and commercial _x000D_ installations in LV networks. They can also be employed in MV networks _x000D_ through the use of a coupling transformer.
