SBW three phases AC voltage stabilizer is a high power adjustable automatic voltage compensation regulating power device. When voltage from support network is varied due to loading current influence, it automatically regulates the output voltageto ensure the normal function of the electric equipments. Compared with other typesof voltage stabilizer, this series product has large capacity, high efficiency, nowaveform distortion, stable voltage regulation and other advantages, it supportswidely load application, instantaneous overload and continuous long work,manual/auto switch, can also provide over voltage、lack phase、phase orderandmachine faulty automatically protection.Conveniently assemble and reliable operating (can be digital display/analog display).
