A voltage stabilizer is a device that stabilizes the output voltage. The voltage stabilizer is composed of voltage stabilization constant voltage, control circuit, and servo motor. When the input voltage or load changes, the control circuit performs sampling, comparison, and amplification, and then drives the servo motor to rotate. The position of the carbon brush of the voltage regulator is changed, and the coil turns ratio is automatically adjusted to maintain the stability of the output voltage.
What is the main purpose of the voltage stabilizer? The voltage stabilizer is used to stabilize the voltage. When the voltage is high, it drops, and the voltage is low, and then rises. When buying a voltage stabilizer, it is recommended that you buy a regulator that is three times larger than the actual power, because the voltage stabilizer must overcome the surge shock of the commercial power supply and the starting shock of inductive loads (such as refrigerators, air conditioners, (Motor and motor) When selecting a contact type automatic voltage regulator, the rated output voltage regulator should have a larger margin than the transfer type automatic voltage regulator.
Check the appearance quality and processing technology. The operation of buttons, switches, etc. should be flexible and reliable. There should be no loose shaking of parts and components, and there should be no rolling sound of objects in the machine, otherwise there will be foreign objects in the machine. Reasonably select the total rated output of the automatic voltage regulator, which is equal to total power of household appliances plus 3. The shape and structure of the automatic voltage regulator are desktop, wall-mounted, dual-use and floor-mounted, etc., and different styles should be selected according to the installation location, main use, and installation capacity.
