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 AHF005 connected in front of the Danfoss VLT® the harmonic current distortion generated back to the mains is reduced to maximum 5% at full load.[!]Forced cooling is not included within IP00 types. Cooling must be secured separately during installation.Specifications:THiD less than 5%Line voltage: 380-415VLine frequency: 50HzFilter current: 325ALine voltage tolerances: +/- 10%Line frequency tolerances: +5% / -1.5%Overload capacity: 160% for 60 sec. every 10 min.Enclosure rating: 00Cooling concept: Forced cooling is not included within the IP00 design.
