Frequency converter is an AC power device that converts the power supply to other frequencies. In the late 1980s, China began to use frequency converter. Because of its energy-saving effect and superior performance, the use of frequency converter continues to rise in China, and it also plays a very important role in the transformation of traditional industry, the improvement of process flow, the improvement of automation level, energy saving and so on

Application
The main purpose of the frequency converter is that the frequency conversion governor controls the speed of the motor.
We convert the voltage and frequency fixed alternating current into voltage or frequency variable alternating current device called frequency converter, short-circuit protection, phase-to-phase short-circuit protection, input phase protection, output phase protection, overvoltage protection, undervoltage protection, temperature protection input and output reverse connection protection, control motor starting current, So if you want to change the speed of the AC motor to change the frequency of electricity, you can accelerate the function is controllable. overvoltage.
