General
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.
