Classic system control panel, interaction with human computers, compatible with human engineering design, one do operation button and one do stop button, simple and easy. The speed of the motor can be controlled by changing the frequency of the motor. You can try. Features: Small size, compact design, space saving do installation. Classic control panel, human-computer interaction, compatible with human engineering design, one do operation button and one do stop button, simple and easy. After installing the inverter, the motor will not immediately increase the current, not only save the cost, but also extend the engine service time. The engine speed can be controlled by changing the motor frequency. Can control the rotation of do front and do rear, and the motor can be set do front and do rear za inverter. Convenient debugging, stepless speed control, easy to meet the needs of different processes, do button to adjust faster or slower motor speed. Saving energy consumption and reducing costs, it can automatically detect the load current and adjust the output voltage to achieve excellent energy saving effect. Built-in cooling fans, low noise and strong wind, hollow housing design, with fine heat dissipation effect. 9 protection design, overload, overheated, overvoltage, low voltage, overcurrent, phase decay, grounding, short-circuit, duct.
