Servo Type Automatic Voltage Stabilizer

Servo Regulators have all a variable transformer which ensures the voltage stabilization(Vr1 to Vr3), servo motor which commands the auxiliary transformer and an electronic card which controls the output voltage.In case like a sudden increase or decrease of normal Line voltage, the electronic control circuit considers it with max.sensibility and let the servo motor move quickly. Whilst the motor, according to the signal it gets; by moving right and left the adjusted transformer (Vr.1 to Vr.3) which it is coupled with; the voltage in the secondary coil will be added or subtracted to / from the primary coil of booster transformer. It keeps the output voltage at constant level with max
(+/-)2% tolerance thus, the other additional auxiliary equipments will ensure material’s safe working. Via control system which includes quick response time, the high start torque AC motor system will quickly correct small voltage variations in the input. When servo motor input voltage working limits are exceeded, the output voltage is set to an automatically preferred level, and it is taken off from the circuit by the control circuit
