EMC filters

Power line filters

  • Wide current range of standard
    filters up to 2500 A
  • Rated voltage up to 760 V AC and 1500 V DC
  • Various terminal styles
  • UL / CSA / ENEC approvals
  • Customer solutions upon request

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
  • UL 1446 Class 155 (F) Insulation
    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



2-line filters

  • Suppression of differential and common-mode disturbances
  • Modular SIFI filter system with various cases and insertion loss performances
  • 1 or 2 stage filters
  • Ambient temperature up to +100 °C
  • Filters for frequency converters
  • VR: 250 … 1500 V DC
