GRIDCON® Active Filter
Active harmonic filters for broad band harmonics reduction
Modular active harmonic filters for any application: Our 4-wire active filter is optimized for filtering single-phase loads, and protects against neutral conductor overloads. Common applications are in 208 V and 400 V networks. The 3-wire variant is designed for industrial applications with symmetrical loads and is available with up to 500 A per control cabinet. Its range of application goes beyond the voltage of 400 V: the filter also improves the voltage quality in networks with nominal voltages of 480 V, 600 or 690 V or reduces harmonics in medium voltage networks via a transformer.
Your Advantages at a Glance
