Motorised Voltage Regulators are devices used to regulate voltage, primarily to protect electrical equipment from voltage fluctuations. They are usually controlled by an electric motor and can stabilise the output voltage by regulating the power input.Motorised Voltage Regulators usually consist of a motor and a regulator that controls the speed of the motor to regulate the output voltage. The regulator typically monitors the power input voltage and adjusts the motor's speed as needed to keep the output voltage stable within a set range.
