- หลักการทำงาน
It consists of a contact auto-voltage regulator, servo motor, and automatic control circuit. When the mains voltage fluctuates, the control circuit samples and amplifies the signal, driving the servo motor to move the carbon brush along the regulator coil, automatically adjusting the output voltage to the rated 220V for stable regulation.
