Ideal for the use of household appliances with inverter output and surge suppression of motors!
Contributing to the reduction of voltage ripple after the output of the inverter section of the solar power generation system" and "suppression of surge voltage when converting old motors to inverters.
The "SWF Series" is a sine wave filter suitable for general-purpose inverters to convert the inverter output voltage into a sine wave. 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 ensures the long lifespan of motors. Our company provides comprehensive support for sine wave generation of inverter output voltage! We can accommodate various requests. - Estimates available for power supply voltages in the 200V class - Estimates available for inverter carrier frequencies of 2kHz - Estimates available for motor operating frequencies of 60Hz and above [Features] - Suppresses surge voltage applied to the motor - Reduces ripple in the inverter output voltage waveform and converts it to a sine wave - Achieves long motor lifespan by suppressing surge voltage Leave the support for sine wave generation to us. *For more details, please refer to the PDF document or feel free to contact us.
