Harmonic Filters

  • Reduction of harmonics and low frequency distortion
  • Improvement of the THD-I values
  • Compliance with the harmonic emission requirements of IEC 61000-3-12
  • Less expensive than active harmonic filters
  • Significantly reduced input current (energy saving)


HFE-A (THD-I <16%*)
HFE-B (THD-I <10%*)

High Performance Harmonicfilter

  • Current ratings from 10 A up tp 400 A
  • For power up to 440 kW
  • 380 V – 690 V (50 / 60 Hz), 3-phasig
  • THD-I up to 5 % is possible (typical 10-16 %*)
  • Especially for devices with B6 – rectifier bridge
  • Reduction up to 50th harmonics (2.5 / 3.0 kHz)
  • Switchable capacitors
  • No leakage current
  • For higher requirements

* at RSCE ≥ 66, THD U ≤ 2%
