The Danfoss Advanced Harmonic Filter is a passive harmonic filter specially designed to match the Danfoss VLT® AutomationDrive, VLT® AQUA Drive and VLT® HVAC Drive frequency converters. With AHF 010 connected in front of the Danfoss VLT®, the harmonic current distortion generated back to the mains is reduced to 0.1 total harmonic current distortion at full load.
