The output voltage of the regulator is stable equipment. Regulators have constant voltage control circuit, and a servo motor and other components. When the input voltage or load changes, sampling control circuit, comparison, amplification, and then drive the servo motor rotation. So that the position of the regulator carbon brush change, by automatically adjusting the turns ratio, so as to maintain a stable output voltage.
What is the purpose of the regulator is? Regulator is to play the role of stabilizing the voltage, high voltage, and it came down, low voltage, and go up again. When buying regulator suggest that you want to buy is three times larger than the actual power of the regulator, because the regulator to start the actual work to overcome the impact of surges and inductive load electricity (such as refrigerators, air conditioners, motor and motor) when selecting contact automatic voltage regulator, the rated output voltage regulator should be left a greater margin than the automatic voltage regulator adapter.
Check the appearance quality and processing. Buttons, switches and other operations should be flexible and reliable, no loose parts shall shake at the parts, there should be no object rolling sound of the machine, otherwise the machine instructions of a foreign body. Reasonable choice of automatic voltage regulator rated output total, total = total power appliances × 3. Automatic voltage regulator outline structure of a desktop, wall-mounted, dual-station wall and floor type and other types, should be placed based on the location of the installation, the main purpose, as well as the ability to install, select a different style.
