The core function of the variable frequency control cabinet is to control the operating speed of the motor by changing the frequency of the power supply, in order to adapt to different working requirements and conditions. This control method can not only reduce energy loss, but also make the equipment start more smoothly, avoiding damage to the motor caused by the large current generated during direct starting.

 Variable frequency control cabinets usually have various functions, such as analog input (for speed control or feedback       signals), PID control, pump switching control (for constant pressure), communication function, macro function (with different parameter settings for different occasions), and multi-stage speed control. Variable frequency control cabinets are widely used in industrial and agricultural production, as well as automatic control of water supply, drainage, fire protection, sprinkler network pressurization, HVAC cold and hot water circulation and other occasions in various buildings.
