1、AUTOMATIC OPERATION: Automatic voltage regulator can automatically detect fluctuations in input voltage and maintain a stable voltage output by automatically adjusting the output voltage. This can effectively defend electronic devices from high or low voltage damage. 2、STABLE VOLTAGE OUTPUT: Automatic voltage regulator can maintain the output voltage unchanged during voltage fluctuations in the power grid. A stable voltage output can ensure the normal and stable operation of the equipment, and improve its work efficiency. 3、EFFICIENT PROTECTION: Automatic voltage regulator is equipped with a built in protection circuit, which can effectively defend the equipment from factors such as induced overcurrent, overvoltage, short circuits, etc. 4、ENERGY SAVING: Automatic voltage regulator adopts electronic control, which can achieve energy conservation, environmental protection, and reduce energy consumption. 5、EASY CARRYING: Comes with a small size and a light weight as well, this AVR is easy to carry around for convenient use.
