Converter chokes and output filters

  • Line reactors
  • dv/dt output reactors
  • Sine-wave filters
  • SineFormer sine-wave EMC output filters for frequency converters supersede shielded motor cables
  • Active front end chokes, DC chokes and dv/dt filters upon request

High-voltage common-mode

  • High DC voltage capability
  • High current handling capability
  • Suppression of asymmetrical
    interferences coupled in on lines. The high-frequency portions of the symmetrical data signal are decreased so far that EMC problems can be significantly reduced
  • Customized designs

    system

High-current common-mode

  • Wide current range up to 62 A
  • High current-handling capability
  • One- and three-phase design
    available
  • Suppression of asymmetrical
    interferences coupled in on lines. The high-frequency portions of the symmetrical data signal are decreased so far that EMC problems can be significantly reduced
  • Customized designs
  • UL 1446 Class 155 (F) Insulation system applicable

Standard common-mode chokes

  • Suppression of asymmetrical interference coupled in on lines. The high-frequency portions of the symmetrical data signal are decreased so far that EMC problems can be significantly reduced
  • Wide range of different core shapes and sizes available, with specific properties
  • High current-handling capability
  • High temperature stability
  • Standard and customized designs
  • UL and VDE certified



3-line filters

  • Mains filters for 3-phase applications with symmetrical load
  • Optimized leakage current
  • Book size or compact filters
  • B84243*****000 high attenuation
  • B84143D****R127 for very high attenation
