SJW - WB series 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.
