The VLT® Advanced Harmonic Filter is a passive harmonic filter specially designed to match the Danfoss frequency converters "VLT® AutomationDrive, VLT® AQUA Drive and VLT® HVAC Drive. With AHF010 connected in front of the Danfoss VLT® the harmonic current" distortion generated back to the mains is reduced to maximum 10% at full load.
