Description
Compensation AC industrial voltage stabilizer / Servo motor controlled AVR:
Model: SBW (three phase), DBW (single phase)
A voltage regulator, also known as an automatic voltage stabilizer (AVR), is a device that maintains a consistent output voltage despite fluctuations in input voltage or load conditions. It comprises three main components: a voltage regulating circuit, a control circuit, and a servo motor.
When the input voltage or load changes, the control circuit continuously monitors the voltage level, compares it to a reference voltage, and amplifies the difference. This signal is then used to drive the servo motor, which adjusts the position of the carbon brush in the voltage regulating circuit. By automatically altering the coil turn ratio within the regulator, the output voltage is effectively stabilized.
