Suppress surge voltage at the motor terminal! Shape the inverter output voltage waveform into a pure sine wave!
The "SWF Series" is a sine wave filter suitable for the sine wave shaping of inverter output voltage for general-purpose inverters. SWF converts the PWM-controlled rectangular output voltage waveform into a sine wave through high-speed switching of the IGBT in the inverter section. This suppresses surge voltage and achieves a longer lifespan for motors. We provide comprehensive support for the sine wave shaping of inverter output voltage. Leave the sine wave shaping support to us. 【Features】 ■ Suppresses surge voltage applied to the motor terminals ■ Converts inverter output voltage waveform into a sine wave ■ Achieves longer motor lifespan by suppressing surge voltage *For more details, please refer to the PDF document or feel free to contact us.
