Application
SBW, DBW three phases AC voltage stabilizer is a contact adjustable automatic voltage compensation high power requlating power device. When voltage from support network is varied due to loading current effect, it automatically regulates the output voltage to ensure the normal function of the varied electrical equipments.

Use Occasion
Widely used in post office and telecommunications, department stores, elevators, hospitals, schools, printing factory, securities and other occasions where normal voltage is a must, such as workshop, mines, medium enterprises, some of the important equipment and computers' power and support
