Sine Wave Filters FN5040HV

LC Sine Wave Filter for 600 VAC and 690 VAC Motor Drives Applications


LC Sine Wave Filter for 600 VAC and 690 VAC Motor Drives Applications

  • Smooth sine wave without voltage peaks
  • Motor protection against pulse pattern stress
  • Improvement of system reliability
  • Reduces bearing currents
  • Ideal for retrofit installations
  • Fits for long motor cable lengths (longer than 2000 m)
  • Motor drive power range up to 1,200 kW

Features and Benefits

Converts the rectangular PWM output voltage of motor drives into a smooth sine wave with low residual ripple
Elimination of premature motor damage caused by high dv/dt, overvoltages, cable ringing, motor overheating, and eddy current losses
Improves bearing life time because of bearing currents caused by circulating currents
Reduces electromagnetic emissions and acoustic noise levels
Eliminates pulse reflections in the motor cable

Typical Applications

HVAC applications
Medium voltage applications, deployed in front of the step-up transformer
Retrofit installations with motor drives
Motor drive with long motor cable
Motor drive with multiple motors in parallel
