DBW . SBW  series  single - phase  and  threephase fullautomatic 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 textileindustry, air-condition, TV set, household appliance and lighting
used for industry, agriculture, traffic, military, railroad, scientific culture, etc, where need voltage stabilization.

Main t echnology characteristics (DBW.SBW series single-phase and three-phase full-automatic compensated voltage stabilizer)

a. Input voltage: Three-phase: three-phase four-wire phase voltage 220±20%,  　　　wire voltage 380V±20% or phase
    voltage 220±30%,  wire  voltage  380V ± 30%, they can be selected ( please  indicate  when  placing  an order)
    Single phase: 220V±20% or 220V±30%, it can be selected ( please indicate when placing an order)
b. Output voltage:
    Three-phase: three-phase four-wire phase voltage 220V, wire voltage 380V
    Single-phase: 220V
c. Accuracy of output voltage: 2-5% (adjustable)
d. Efficiency: ≥95% ( power class: more than 50KVA)
e. Response speed: ≤1.5S (when outside voltage has 10% of change)
f. Waveform distortion: no additive waveform distortion
g. Protection : protection  against  over  voltage ,  over  current ,  phase  failure  and machine fault, as well as phase
    sequence protection (single-phase and three-phase 150KVA below  has  no  phase  failure  and  is  provided with
    phase sequence protection).
h. Voltage stabilization, convenient switching for commercial power (single phase has no function)
i. Start automatically or by hand (can be chosen) when power is on.
h. Can work continuously for a long time without anybody attending.
k. Insulation resistance: ≥2MΩ
l. Electric strength: bear power frequency sine voltage 2,000V for 1 min without breakdown or flash over.
m. Overload capability: 2 times rated current, keeping 1 min (voltage stabilizer special for elevator and CT)
