VLT® AHF 005 & AHF 010 Harmonic Filters

VLT® AHF 005 & AHF 010 Harmonic Filters

The VLT® Advanced Harmonic Filter AHF 005 and AHF 010 are advanced harmonic filters not to be compared with traditional harmonic trap filters. The Danfoss harmonic filters have been specially designed...

Power Range

  • 380 - 415V, 50Hz, 10 - 480A
  • 380 - 415V, 60Hz, 10 - 480A
  • 440 - 480V, 60Hz, 10 - 436A
  • 600V, 60Hz, 15 - 395A
  • 690V, 50Hz, 15 - 395A
Features and Benefits
Ambient temperature 5° to 45°C without derating
Overload capacity 160% for 60 sec every 10 min.
Enclosure degree IP00 and IP20
Convection cooling is not possible with IP00 types and a forced airflow must be engineered as part of the mounting concept.
IP21/NEMA 1 kit is optional for IP20 enclosures
  • Mounting
  • Side by side mounting with the drive
  • Paralleling possible for higher current range
Approvals
  • CE
