Three-Phase 380V Frequency Converter 7.5KW-450KW

It is designed for screw and piston air compressors to solve the problems of "frequent start and stop at power frequency and high no-load energy consumption" of traditional air compressors. By precisely adjusting the speed to 0.01Hz, the air compressor's exhaust volume can be matched in real time with the gas demand. For instance, when pneumatic equipment in an automotive factory operates intermittently, the air compressor can run from 50Hz to 20Hz, reducing the no-load energy consumption from 30% to less than 5%, and achieving an electricity-saving rate of 30% to 45%. After the 75kW air compressor of a certain auto parts factory was renovated, it saved over 120,000 kilowatt-hours of electricity annually. The soft start function can prevent the current impact when the air compressor starts (the traditional direct start current can reach 5 to 8 times the rated value), protecting the stability of the compressor head and the power grid. It is equipped with an internal pressure PID regulat…
