Optimize harmonic performance
Advanced Harmonic Filter AHF 005/010 is a cost-effective total solution, the package combines the reliability and performance of VLT® Series drives with the innovative technology of AHF Series Filters.
Compared to traditional harmonic trap filters AHF offers a smaller foot print and higher harmonic reduction.
The solution is available in two variants, AHF 005 and AHF 010. When connected in front of a Danfoss VLT® drive, the harmonic current distortion generated back to the mains is reduced to 5% and 10% Total Harmonic Current Distortion at full load.
With a >98% efficiency the passive Advanced Harmonic Filters offer cost effective and very robust harmonic solutions specifically for power up to 250 kW.
As stand-alone options the Advanced Harmonic Filters feature a compact housing that is easily integrated into existing panel space. This makes them well-suited for retrofit applications with limited adjustments of the frequency converter.
