  • Product introduction
  • Technical parameter
  • Product specification
  • Water-cooled frequency conversion speed regulating device (hereinafter referred to as frequency converter) adopts unique soft charging technology to precharge the power unit capacitor in the frequency converter by controlling the power supply and effectively eliminate the excitation inrush current. Does not affect the upper high voltage switchgear, does not affect the power unit in the DC capacitance, prolong the service life and reliability of the capacitor.
