Water-cooled variable frequency speed regulation device 2

The water-cooled variable frequency speed control device (hereinafter referred to as the inverter) adopts a unique soft charging technology, which precharges the power unit capacitor in the inverter by controlling the power supply, effectively eliminating the excitation inrush current. It does not affect the superior high-voltage switchgear, does not affect the DC capacitor in the power unit, and prolongs the service life and reliability of the capacitor.
