DBW SBW Compensated Voltage Stabilizer
DBW SBW compensated voltage stablilizer is a contact adjustable automatic voltage compen-sation high-power regulating power device. When voltage from supply network is varied or dueto loading current effect, it automatically regulates the output voltage to ensure the normal func-tion of the varied of electric equipments.
