| Product Specifications | Applicable to cage AC asynchronism motor,synchronous motor and winding induction motor of three-phase 50 Hz, rated voltage 280 V,rated power 30 KW-400KW;usually applicable to the motors used for water pumping stations,blower fans,conveyors, reducer, ball mill and such as the equipments,especially for the motor needing to be operated with frequent and long-term changing-load or light-load.
Solid soft start is an electrical System adopting a dual CPU for the management centre,a large-scale integrated circuits for the control of the device and high-power thyristor for the main circuit control devices.Microprocessor issues the ˇůtriggerˇěpulse to add to the trigger of six thyristors to control on-angle of thyristor so that the output voltage of thyristor is controlled by the ˇůtriggerˇě pulse of the phase angle,raises from zero to full voltage and motor speed raises from zero to rated speed to make the motor soft start.
