Tips: What is a Voltage Stabilizer?
Voltage stabilizer is a kind of power supply equipment which can automatically adjust the output voltage. Its function is to stabilize the power supply voltage which fluctuates greatly and cannot reach the requirement of electrical equipment within its set value range, so that various circuits or electrical equipment can work normally under rated working voltage. With the increasing number of household electrical equipment, the use of voltage stabilizer is more and more extensive. Domestic voltage stabilizer is mainly used to stabilize the voltage of TV, refrigerator, air conditioner, etc.
500 VA single phase AC automatic voltage stabilizer is based on relay control system & programmed control computerized technology for home purpose. It has many unique features which enable it to give high performance, better reliability and save electricity.
