DJW-WB.SJW-WB Microcomputer Contactless Compensation Voltage Regulator.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 timedelay, 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 transientrunning of system and unit, has strong instantaneous overload ability, so it can greatly improve the reliability of system operation. Performance: Range of input voltage: single-phase 176-264V three-phase 304-456V Output voltage: single-phase: 220V three-phase: 380V Accuracy of voltage stabilization: 2.5% Frequency: 50Hz/60Hz load power factor: >0.7 Efficiency: >95% Strain time: 0.2 0.5S Instantaneous overload: 1.5-2 times of the Rated Current Advantage: Contactless, no noise, no machinery and carbon brush abrasion With the function of protection against over voltage, under voltage and phase failure, fault diagnosis, signal display,alarming. Common Specifications: single-phase 10KVA 100KVA, three-phase 10KVA - 300KVA. if you have any requirments special specifications pls contact with us.
