Specifications and Features

The sine wave filter for a higher frequency of 450Hz is designed in a perfect sine wave form to provide the highest level of protection to the motors by converting the output of the VFD into a value that is closest to a sine wave. The performance and efficiency of this filter is higher than that of the existing LC filter. And, they are designed to provide a sine wave form output voltage when operated by a PWM inverter with a conversion frequency of 4kHz to 16kHz.
