Comprehensive support for the sine wave of inverter output voltage! Easy selection of models according to the site!
The "SWF Series" solves issues such as surge voltage, shaft electrical erosion, and leakage current by converting the rectangular output voltage waveform of the inverter's PWM control waveform into a sine wave. To convert the PWM control waveform into a sine wave, high-frequency components such as carrier frequency are cut. This reduces surge voltage and contributes to the longevity of the motor. Additionally, it also reduces leakage current from cables. 【Features】 ■ Achieves longer motor lifespan ■ Supports long-distance cables ■ Standardized wide lineup ■ Corrects voltage distortion in the inverter output circuit *For more details, please refer to the PDF document or feel free to contact us.
