Product Description

Automatic servo-controlled AC voltage stabilizer is a device used to regulate the voltage of alternating current (AC) power to maintain a consistent output voltage level, regardless of fluctuations in the input voltage.

Here's how it typically works:


1. Input Voltage Sensing: The stabilizer continuously monitors the input voltage from the power source.

2. Comparison: It compares the input voltage with the desired output voltage level.

3. Control Signal Generation: Based on the comparison, the stabilizer generates a control signal that determines the required adjustment to the output voltage.

4. Servo Motor Operation: The control signal drives a servo motor, which adjusts the position of a variable transformer or other voltage control mechanism.

5. Voltage Correction: The movement of the servo motor adjusts the voltage until the output voltage matches the desired level.

6. Feedback Loop: The stabilizer continuously adjusts the voltage by receiving feedback from the output to ensure that it remains stable.
