AVR series high-precision fully automatic AC voltage regulator is composed of a contact type voltage Stabilizer, servo motor, microcontroller control system, etc. When the power grid voltage is unstable or the load changes, the automatic sampling control circuit sends a signal to drive the servo motor, adjust the position of the voltage regulator carbon contact, and adjust the output voltage of the regulator to the rated value and reach a stable state. Equipped with LCD display, overvoltage, overcurrent, over temperature protection functions, and can be customized with long delay and undervoltage protection according to user needs.
This series of voltage regulators has complete specifications and beautiful appearance; It has the characteristics of undistorted waveform, high efficiency, stable output voltage, and long-term operation. It can be applied to any facilities to ensure safe and reliable operation of electrical equipments.
