A Servo Stabilizer, also known as a Servo Voltage Stabilizer, is an electrical device designed to automatically maintain a stable voltage level to protect electrical equipment from voltage fluctuations.
A servo stabilizer uses a servo motor-controlled mechanism to regulate voltage. When the input voltage fluctuates from the desired range, the servo motor adjusts an auto-transformer, which in turn corrects the output voltage to a safe and consistent level. This process happens continuously in real-time.
