A Servo-Controlled Voltage Stabilizer is an automatic Voltage Regulator that uses a servomotor to achieve highly precise voltage stabilization. When the input voltage fluctuates, a control circuit detects the change and commands the servomotor to adjust a variable transformer. This physical adjustment adds or subtracts voltage from the input, ensuring the output voltage remains within a very tight tolerance, typically ±1%. This makes it ideal for protecting sensitive industrial, medical, and laboratory equipment.
