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).

Advanced Magnetic Design: 

Utilizing a dry-type iron core design with multiple air gaps, these sine wave filters effectively prevent magnetic saturation, achieving high linearity across the entire switching frequency range.

Total Motor Insulation Protection: 

Raytech sine wave filters smooth the inverter output into a pure sine wave, providing comprehensive motor insulation protection for your motor.

Noise Reduction: 

By removing high-frequency carrier components, our filters can almost completely eliminate motor "magnetic noise," making them ideal for applications in noisy working environments.

Flexible Switching Compatibility: 

Optimized specifically for carrier frequencies from 3kHz to 10kHz, these filters are compatible with most modern inverter models.
