SIKES Advanced Passive Harmonic Filter PHF 005 and PHF 010 are robust and easy-to-use passive harmonic filters that reduce harmonics while maintaining good system energy efficiency.

Optimize harmonic performance

Advanced Harmonic Filter PHF 005/010 is a cost-effective total solution. Compared to traditional harmonic trap filters PHF offers a smaller foot print and higher harmonic reduction.

The solution is available in two variants, PHF 005 and PHF 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. (System requirements: THVD < 2%, line voltage unbalance < 1%)

With a >98% efficiency the Advanced Passive Harmonic Filters offer cost effective and very robust harmonic solutions specifically for Danfoss VLT® drive 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.
