Advanced Harmonic Filter
The Danfoss AHF 005 and AHF 010 are advanced harmonic fi lters, not to be compared with traditional harmonic trap fi lters. The Danfoss harmonic fi lters have been specially designed to match the Danfoss frequency converters.
By connecting the Danfoss harmonic filters AHF 005 or AHF 010 in front of a Danfoss frequency converter, the a Danfoss frequency converter, the rated back to the mains is reduced to a minimum.
Calculation Software
Danfoss has created a PC based program MCT31 for calculation of harmonics with different principlesfor suppression. It can calculate the harmonics for danfoss frequency converters depending on actual system (transformer, cables, other loads, etc.)
