Advanced Harmonic Filter AHF 005/010 is a cost-effective total solution, Danfoss Advanced Harmonic Solutions packages which combines the reliability and performance of VLT® Series drives with the innovative technology of AHF Series Filters.
Compared to traditional harmonic trap filters they offer 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.
Designed for matched performance with Danfoss VLT® Series drivesUser-friendly startup; no adjustment necessaryRequires no routine maintenanceProtects multiple drives with one filterDesigned to address the current distortion limit guidelines of IEEE 519-1992AHF 10 has THiD < 10%; equal or superior performance and cost competitive compared to 12-pulse rectifiersAHF 05 has THiD < 5%; equal or superior performance and cost competitive compared to 18-pulse rectifiers

With VLT® Motion Control Tool MCT 31, you can determine whether harmonics will be an issue in your installation when drives are added.
MCT 31 estimates the benefits of adding various harmonic mitigation solutions from the Danfoss product portfolio and calculates system harmonic distortion. Furthermore the software provides quick indication of whether the installation complies with the most recognized harmonic norms and recommendations.
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.
