Frequency converter is an AC electricity computer that converts the electrical energy supply to unique frequencies. In the late 1980s, China commenced out to use frequency converter. Because of its energy-saving influence and last performance, the use of frequency converter continues to upward jab in China, and it moreover performs a very essential function in the transformation of regular industry, the enchancment of device flow, the enchancment of automation level, electrical energy saving and so on.

Application
1. The frequency converter has the soft starting function, which reduces the impact of the motor on the power supply grid during the starting process
2. Frequency converter has good speed control function, which can convert 58 Hz power frequency through a series of conversion, so that its output frequency can be variable, and the motor speed control can be automatically completed
3. With communication function, convenient man-machine exchange, and plc barge can realize automatic control
4. With perfect electrical protection function
