SJW-WB．DJW-WB Series single-phase and three-phase microcomputer-controlled non-contacting compensated power voltage stabilizers(hereinafter called as voltage stabilizer)，the newest highpower AC regulated power supply，are designed according to tile actual conditions in our country，importing the newest technology of international AC regulated power supply．Taking the advanced combination winding compensated and non-contacting switch and the technology of microprocessor control AC stabilized voltage as the integral．the power voltage stabilizers own the features of high efficiency，energy-saving，quick regulation，automatic balancing for three phase，non-maclmical fault and lion- wear to carbon brush，time-delay，and the functions of alarm and protection to over-and undelvoltage，etc．Meanwhile．the power voltage stabilizers is the first to get rid of the commonmode current rush of non-contacting switch caused during the transient operation of system and equipment and the damage because of the overvoltage．It is high in instantaneous overload，which greatly improves the reliabflity of system operation．
