Harmonic Filters

  • Reduction of harmonics and low frequency distortion
  • Improvement of the THDi values (<5% possible)
  • Compliance with the harmonic emission requirements of IEC 61000-3-12
  • Less expensive than active harmonic filters
  • Significantly reduced input current (energy saving)


HFE-5P (THDi <5%*)
HFE-8P (THDi <8%*)

High Performance Harmonicfilter

  • Current ratings from 10 A up tp 410 A
  • For power up to 250 kW
  • 380 V – 690 V (50 / 60 Hz), 3-phasig
  • THDi 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, THDU ≤ 2%
