Product features
1, Aluminum Alloy shell or plate welding, surface spray;
2, in the Fuji, SIEMENS or Schneider and other companies produce inverter, circuit breakers, ** lights and other components;
3, it is mainly through the change of its output frequency to adjust the speed of ordinary three-phase asynchronous motor, in order to achieve the production process requirements or achieve the purpose of power saving, power saving rate of up to 60% a 30%, also
Can be used as a motor soft starting controller, but also through the sensor, transmitter and other control circuit to form a closed-loop speed control system, the installation is simple, constant power factor, at the same time with the fault
Display and other functions;
4, with over current, short circuit, over voltage, under voltage, broken equal protection, digital display frequency, speed and load rate or current, etc., can manually adjust the frequency, can set the speed
Time varying process curve. Can also be given by the DC'S system ** to control its frequency;
5, steel pipe or cable wiring
