DBW . SBW  series  single - phase  and  three - phase  full - automatic  compensated voltage stabilizer (hereinafter referred  
to as voltage  stabilizer )  is designed  for stabilizing AC voltage and made with Western Europe advanced technology and on 
the  basis  of  our  country  national  conditions .  It   can  keep  output  voltage  in  steady  state automatically when the power 
network voltage fluctuates or the load current varies.  Compared  with  other voltage stabilizers, it has the advantage of large 
capacity, high efficiency, no  wave  distortion,  stable  voltage  adjustment, suitability  for kinds of  loads,  bearing  instantaneous  
overload,  working  continually for long time, as well as free transferring  between  manual  control  and  automatic  control,  
etc,  besides,  it is provided with protection against over-voltage,  over  current,  phase  failure  and  protection  for  phase  
sequence  and  has  following  merits: small volume,  light  weight,  convenient  installation  and  reliable  running and so on.  
It  can  be  applied  to  large type electromechanical  equipment,  metal  processing equipment, production line , construction  
device , elevator , medical  equipment, equipment of light and textile industry, air-condition, TV set, household appliance and 
lighting used for industry, agriculture, traffic, military, railroad, scientific culture, etc, where need voltage stabilization.
