Converter Solutions

Sine Wave Filters

The products are specially designed for VFD to protect the motors. It is used at the output side of frequency converters and converted the PWM output signal of motor into a smooth sine wave form. Besides it reduces the resonance phenomenon caused by distributed capacitance and inductance of the long cable (longer than 50 meters).
