Overview:The water-cooled variable frequency speed regulating device (hereinafter referred to as the inverter) adopts a unique soft charging technology to precharge the power unit capacitor in the inverter by controlling the power supply, effectively eliminating the excitation inrush current. It does not affect the upper-level high-voltage switch cabinet or the DC capacitor in the power unit, extending the service life and reliability of the capacitor.

Overview:Forced air-cooling frequency conversion speed regulating device, the capacity range is 250KVA - 15MVA. It adopts modular combination design of power units, air-cooling method, high power density, and easy maintenance and installation. Suitable for LNG, wind tunnels, long-distance pipelines, chemical industry, metallurgy, power generation, cement and other fields.
