This type of filter is more expensive than passive filters, but much more complete in terms of their settings.


Ease of installation for dimensions 

Range for 3-wire (3W model) or 4-wire (4W model) installations.

Voltage and frequency multiplication (50/60 Hz).

Reduction of harmonic currents up to order 50 (2500 Hz).

Selectable harmonic frequencies to be filtered for greater filter efficiency.

Reactive power compensation (inductive/capacitive).

Phase current balancing
