DJW - WB, SJW - WB  series  single - phase  and  three - phase  microcomputer  contactless  compensation voltage stabilizer  
( hereinafter referred to as voltage stabilizer ) is  the  latest high - power  AC  voltage  stabilization  power supply,  designed  
with  the  international  advanced  technology and on the basis of our country national conditions. It integrates  sophisticated  
compensation  mode  of  compound  windings,  contactless  switch  and  technology  of  microcomputer  control  AC  voltage 
regulation, has the features of high efficiency, energy-saving, fast adjustment, automatic balance of three phases, no 
machinery malfunction or carbon brush wearing and has the function of time delay,  over voltage or under  voltage  alarming  
and protection. In addition, this voltage stabilizer can successfully prevent  contactless  switch  being  damaged  for  co - state  
current impact and over voltage produced by transient  running  of system  and unit,  has strong instantaneous overload ability,  
so  it  can greatly improv e the reliability of system operation.
