The frequency conversion control cabinet is mainly used to adjust the working frequency of the equipment, reduce energy loss, start the equipment smoothly, and reduce the damage to the motor caused by the large current generated when the equipment is directly started. At the same time, it comes with analog input (for speed control or feedback signal), PID control, pump switching control (for constant pressure), communication function, macro function (different parameter settings for different occasions), multi-stage speed and so on It can be widely used in industrial and agricultural production and automatic control of water supply, drainage, fire protection, sprinkler pipe network pressurization, HVAC hot and cold water circulation and other occasions
