DBW and SBW Single-Phase and Three-Phase High-Power Voltage Regulator 

            

     

Introduction:This series large power voltage stabilizer is an energy-saving new product developed by our company by absorbing the advanced technology ofWestern 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

Service Occasions :Widely used in the fields of post office, store, elevator, hospital, school, publishing house and stock exchange where normal voltage is in need, and also can be used in the factories of large and middle-scale industrial and mining corp. It is very much suitable for some important devices and supporting single machine.
