VFD Technology:

Variable Frequency Drive is to change the power supply frequency, thereby adjusting the load, reducing power consumption, reducing losses, and extending the service life of the equipment. The core of the VFD technology is the frequency converter, which realizes the automatic adjustment of the running speed of the motor through the conversion of the power supply frequency, and changes the fixed grid frequency of 50Hz to a changing frequency of 30-90Hz. In addition, it can widen the adaptable range of the power supply voltage to 142-270V, which solves the problem of affecting the operation of electric equipment due to the grid voltage instability. The technology that realizes AC control by changing the AC frequency is called VFD technology. Note: Customized products are available according to special needs.
