ZTY Three Phase


When the utility is not stable or the load fluctuates, the Automatic Control Circuit modifies the Control Output according to the Output Voltage change of power supply, which is used to drive the Servo Motor, and then the Servo Motor adjusts the carbon brush of Auto-Transformer to maintain the Output Voltage at its rating and remain stable.
