Woonyoung WYSWF404 Sine-Wave Filter, Vertical, 450 Hz, 200-355 kW

Woonyoung WYSWF404 Sine-Wave Filter, Vertical, 450 Hz, 200-355 kW

Open-frame vertical sine-wave output filter for high-speed 400 VAC (Umax 500 V) inverter drives up to 450 Hz output, 4-16 kHz switching, 200-355 kW.

Key features

  • LC filter that converts PWM inverter output into a near-sinusoidal voltage for the motor
  • Protects motors from insulation stress, overheating and bearing damage caused by PWM voltage
  • Allows long motor cables and reduces audible motor noise and EMI
  • Harmonic voltage distortion max. 5%
  • Alarm contact N.C. 150 C (TH1-TH2) on wall-mount models
  • CE and RoHS marked
