The variable frequency control cabinet converts fixed frequency AC power into adjustable frequency AC power through its built-in frequency converter.
The frequency conversion control cabinet can accurately control the motor speed and improve energy utilization efficiency by changing the power supply frequency.
Advantages And Characteristics:
- Under light or no-load conditions, the speed of the motor can be reduced, thereby significantly reducing energy consumption. According to statistics, the energy-saving rate of using a variable frequency control cabinet is generally around 20% -45%.
- The variable frequency control cabinet can maintain a constant speed under different load conditions, thereby improving production efficiency.
- The variable frequency control cabinet can reduce the wear and tear of motors and mechanical equipment, lower maintenance frequency and costs by controlling the running time and current fluctuations.
- The accuracy of variable frequency control motor speed is improved, so it can keep the system pressure change of the pipeline network within the range of 3pisg, that is, within the range of 0.2bar, effectively improving the quality of the working conditions.

Application area:
- Water supply system: Variable frequency control cabinets are widely used in various urban and rural tap water supply systems, achieving automatic control of closed-loop constant pressure water supply, domestic water supply, fire water supply, and industrial water supply.
- Elevator control: Variable frequency control cabinets provide smooth start and stop as well as accurate speed control in elevator and lift applications, thereby enhancing protection and passenger comfort.
- HVAC system: In heating, ventilation, and air conditioning systems, the variable frequency control cabinet adjusts the operating speed of fans and pumps to maintain a stable indoor environment and reduce energy consumption.
- Power system: Variable frequency control cabinet can achieve dynamic current regulation and optimize power load distribution in power dispatching, reduce power equipment losses, and improve power transmission efficiency.
- Water treatment system: The frequency conversion control cabinet can automatically adjust the motor speed according to the actual needs of the sewage treatment pump, reduce waste, and ensure the quality of treated water.
- Paper and textile industry: The application of variable frequency control cabinets in these industries can improve the automation level of production lines, reduce material waste and improve product quality by accurately controlling the operating speed of machines.
