Advanced Harmonic Filter

Advanced Harmonic Filter


Danfoss Industries offers model AHF 005 and AHF 010 Advanced Harmonic Filters, which are not to be compared with traditional harmonic trap filters. The Danfoss harmonic filters have been specially designed to match the Danfoss frequency converters. By connecting the Danfoss harmonic filters AHF 005 or AHF 010 in front of a Danfoss frequency converter, the harmonic current distortion generated back to the mains is reduced to a minimum. Danfoss advanced harmonic filters offer cost effective and very robust solutions specifically for the low power range. Product range: line voltage – 380-415 V AC (50 and 60 Hz), 440-480 V AC (60 Hz), 500-525 V (50 Hz), 690 V (50 Hz); filter current – 10 A-390 A (modules can be paralleled for higher power); and enclosure degree – IP 20.

  • Line voltage – ±10%
  • Frequency – ±5%
  • Overload current – 160% for 60s
  • Efficiency – 0.98
  • True power factor – 0.85 @ 50% load, 0.99 @ 100% load, 1.0 @ 150% load
  • Ambient temperature – 5ºC-40ºC without derating

  • User-friendly – small compact housing
  • Easy to use in retrofit applications
  • One filter module can be used for several frequency converters
  • Complies with IEEE 519-1992 and stage 1 of EN 61000-3-12
  • Easy commissioning; and no routine maintenance required
