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.
The stabilizer continuously monitors the incoming voltage using a control circuit. It detects any voltage fluctuations (high or low) from the ideal level.
Based on the sensed voltage, the servo motor adjusts the position of a variable transformer (variac). This corrects the output voltage to maintain a stable level, which is then supplied to the connected equipment.
Drives the auto-transformer to regulate voltage.
Adds or subtracts voltage from the supply.
Monitors incoming voltage and sends signals to adjust the servo motor.
Alters voltage as needed to stabilize output.
Ensures smooth contact on the transformer tap.
