SBW series three-phase voltage stabilizer is a contact adjustable automatic voltage compensation high power regulating power dvi
Feature
SBW series three-phase voltage stabilizer is a contact adjustable automatic voltage compensation high power regulating power dvice.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 of electric equipments.
It is an energy-saving new product developed by our company by absorbing the advanced technology of Western Europe. It is provided with two systems of manual/automatic dual control, direct output and stabilizing output,with the functions of over/under-voltage protection, delay and error protection etc, it is reliable and suitable for any load
Application
Widely used in post and telecommunications,department stores, elevators, hospitals,schools, printing,securities and other occasions where all need normal voltage to ensure, such as workshop mines medium enterprise, some of the important equipment and compute power and support
