The Variable frequency control panel converts fixed frequency AC power into adjustable frequency AC power through its built-in frequency converter.
The Variable frequency control panel can accurately control the motor speed and improve energy utilization efficiency by changing the power supply frequency.
Advantages And Characteristics:
- The variable frequency control panel reduces energy consumption and achieves energy-saving effects by adjusting the operating frequency of the motor, usually saving 48.8% of electricity.
- The frequency converter in the control cabinet can enable the motor to obtain a larger starting torque with a smaller starting current, reducing the impact on the power grid and other equipment.
- The cabinet of the variable frequency control cabinet is designed with display devices and operation panels, which can intuitively display the operating status of the variable frequency control cabinet, making it convenient for operators to control the operation of the variable frequency device.
- The frequency converter of the variable frequency control cabinet reduces the impact on the electrical and mechanical components of the motor by adjusting the starting acceleration time, thereby extending the service life of the motor.

Application area:
