A roller-type servo voltage stabilizer is a type of voltage regulation device used to maintain a stable output voltage for electrical equipment. It operates on the principle of servo motor technology combined with a roller mechanism.

Here's how it works

Servo Motor The stabilizer is equipped with a servo motor that continuously monitors the input voltage.
Roller Mechanism Inside the stabilizer, there's a roller mechanism connected to the servo motor. This roller mechanism adjusts the position of the voltage regulator's carbon roller based on the input voltage level.
Voltage Regulation As the input voltage fluctuates, the servo motor and roller mechanism work together to move the carbon roller along the voltage regulator's winding, adjusting the output voltage to maintain it within a predefined range.
Accuracy They provide protection against unbalanced voltage, high voltage surges, and low voltage sags, ensuring a stable and consistent voltage supply to connected equipment.
Overall, roller-type servo voltage stabilizers are widely used in industries where stable voltage supply is critical for the efficient and safe operation of electrical equipment.
