Definition: It is to change the frequency of power supply, so as to adjust the load and play a role in reducing power consumption, reducing loss and prolonging the service life of equipment.

Principle: The core is the frequency converter, which realizes the automatic adjustment of the motor speed rate through the conversion of the power supply frequency, and changes the fixed power grid frequency of 50Hz to the changing frequency of 30 to 130Hz. At the same time, the adaptive range of power supply voltage reaches 142 to 270V, which solves the problem that the instability of power grid voltage affects the work of electrical appliances. The technology of realizing AC control by changing AC frequency is called frequency conversion technology.

Function:

1,. High stability and reliability. Voltage output and frequency output are stable, electromagnetic compatibility design is reasonable, and protection function is perfect.

2. The automatic tuning function is powerful.

3. Support multiple test modes, which can not only find the resonance point quickly, but also control the test process through manual voltage regulation, with higher safety.

4. Man-machine interface.

5, the protection function is perfect.
