DBW Single Phase, SBW  three phases AC voltage stabilizer is a contact adjustable automatic voltage compensation high-power
regulating power device. When voltage from supply network is varied or due to loading current effect, it automatically regulates the
output voltage to ensure the normal function of the variety of electric equipments.
