GRIDCON® Active Filter

Modular active harmonic filters for any application: The flexible design of our GRIDCON® ACF X-Wire filters enables operation in 3-wire and 4-wire applications. A configuration suitable for 4-wire operation – with a mandatory neutral wire connection – is needed to filter single-phase loads, and protects against neutral conductor overloads. Common applications are in 208 V and 400 V networks. In most industrial applications, a 3-wire configuration works best as the design can be optimized for symmetrical loads and no neutral conductor needs to be accounted for.

Our filter for heavy-duty applications is therefore called GRIDCON® ACF 3-Wire and is only available in this configuration. The robust design enables it to operate in the most challenging environments, where it can be used to improve the voltage quality in networks with nominal voltages of 440 V, 480 V, 525 V, 600 or 690 V – Or even reduce harmonics in medium voltage networks via a transformer. The latter plays a vital role in achieving grid code compliance for industrial sites at the point of common coupling with the public grid.
GRIDCON® ACF 3-Wire systems with liquid cooling are optionally available.
