IP00 380VAC 5A-1000A Sine Wave Filter For VFD Frequency Converter

sine wave filters for vfd frequency converter

Sine Wave Filter (SFR)

Sine Wave Filter are designed to provide a Sine Wave output voltage when driven from Variable Frequency Drives or other types of PWM inverters with switching frequencies from 2kHz to 8kHz. For Variable Frequency Drive (VFD) applications, Sine Wave Filters eliminate the problem of motor/cable insulation failures, heating, and audible noise. Sine Wave Filters also reduce electromagnetic interference (EMI) by eliminating the high dV/dt associated with inverter output waveform. Bearing currents are also reduced, especially in larger motors above 50 kW.

Products and appications:

Grab the PWM wave generated by the inverter to a sine wave

Reduce eddy current oss and motor noise of the motor.

Reduce puse current on the output cabe and in the motor to extend the ife of the motor.

onger cabe connection between the inverter and the motor.

Reduce externa radiation. Unshieded cabes can be used in certain occasions, reducing the requirements for fied wiring.

Reduce harmonic content of power suppy and reduce conductive interference.
