Voltage stabilizer:DJW-WB.sJW-WB series single-phase and three-phase microcomputer contactless compensation voltage stabilizer [Clicked:174] 
General (DJW-WB.sJW-WB series single-phase and three-phase microcomputer contactless compensation voltage stabilizer)
    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.
TYPE SELECTION (DJW-WB.sJW-WB series single-phase and three-phase microcomputer contactless compensation voltage stabilizer)
This series of products for the three-phase four-wire, phase adjustmentWay connected to the system, the reliability of the zero line Demanding, it should be noted that the zero -line cross-sectional systemSelect the area to minimize the zero line of contactResistance.
Selected in this series product, the load device currentShall not exceed the product of the rated current value; such as making With perceptual motor type loads, its power not to super -This product is power-off 1 / 6.
This series of product input and output between the non-isolation,Please note that to prevent static electricity.
