The frequency conversion control cabinet is mainly used to adjust the working frequency of the equipment, reduce the energy loss, can start the equipment smoothly, and reduce the damage to the motor caused by the big current when the device is started directly. At the same time with the analog input (speed control or feedback signal), PID control, pump switching control (for constant pressure), communication function, macro function (according to different occasions with different parameters), multi speed etc..
