Active Harmonic Filter

Complete Technical Specifications

The AHF is used to correct voltage and current harmonics generated within an industrial facility to reduce Total Harmonic Distortion THD to acceptable limits. It is a conventional current controlled Active Harmonic Filter for use up to 690V at either 60Hz or 50Hz.

Industrial applications where loads within the facility are creating harmonic currents over a wide frequency range. AHF can also be used to correct power factor where this is fluctuating with time.

Available for 60Hz at 208V, 480V and 600V.

Available for 50Hz at 200V, 400V and 690V

Rugged Industrial design

Smaller units to 25-100A available as wall mounting

Larger Units to 600A (or more) as compact floor standing cubicles

"The results were dramatic. Productivity losses from sags with the protected saws were reduced to zero. I can say with absolute confidence the payback was well under a year. Now my only problem is that production managers want to know why we didn’t protect the rest of the wire saws with the AVC. Every time a thunderstorm appears in our area, we have to shut down the unprotected saws until the storm passes.”
