multiind - Filter circuit reactors

To prevent resonance phenomena caused by harmonic content in the power supply system, filter circuit reactors are required to set up detuned compensation systems. Here, high linearities guarantee the necessary functional stability even in the overload range.

Highlights

  • Power from 2.5 to 75 kvar
  • High linearity, low power dissipation
  • Overload protection through temperature switch
  • Low-noise through impregnation
  • Long working life
  • Improvement of impedance behavior
