Non-Contact Compensating AC Voltage Stabilizer
Continuously monitoring the input voltage of the power grid line, the voltage detection unit converts any voltage changes into digital signals. These signals are then processed by the microcontroller, guided by preprogrammed instructions and predefined data. The intelligent control system then transmits commands to the optocoupler, activating the contactless and swift electronic switching circuit to precisely adapt the output voltage. This ensures that the output voltage remains within the acceptable error range, effectively maintaining automatic voltage stabilization.
