High Power Frequency Converter 380V 7.5KW-450KW

For the design of passenger elevators, freight elevators and escalators, the problems of "jerking at power frequency start-up and high energy consumption" of traditional elevators are solved. By adopting vector control technology, the starting speed smoothly rises from 0, enhancing the stability of elevator operation by 30% and significantly improving passenger comfort. When braking, decelerate smoothly through the speed ramp to avoid the car shaking caused by sudden stops. Based on dynamic speed regulation according to load changes, it operates at a reduced speed when moving up empty and uses gravitational potential energy to feed back electrical energy when moving down fully loaded, achieving an electricity-saving rate of 20% to 35%. After the renovation of a 15kW escalator in a certain shopping mall, the average monthly electricity savings exceeded 2,000 kilowatt-hours. It is equipped with dedicated elevator-specific protection functions (such as elevator protection and overload pro…
