VFD 7.5KW 11HP Three-phase380v Vector Inverter Frequency Converter

The vector frequency converter is a power control device that uses frequency conversion technology and microelectronics technology to control the AC motor by changing the frequency of the motor's operating power supply. The frequency converter is mainly composed of rectification, filtering, inverter, braking unit, drive unit, detection unit, micro processing unit etc. The frequency converter adjusts the voltage and frequency of the output power supply by switching off the internal GBT, and provides the required power supply voltage according to the actual needs of the motor, thereby achieving the purpose of energy saving and adjustment. In addition, the frequency converter also has many protection functions, such as overcurrent, overvoltage, overload protection and so on. With the continuous improvement of industrial automation procedures, frequency converters have also been widely used.
