Detailed Description

SJW-WB, DJW-WB series single-phase and three-phase microcomputer-controlled contactless compensation voltage stabilizer is the newest high-power AC regulated power supply, its design is according to the newest technology of international AC regulated power supply. Taking the advanced combination winding compensated & contactless switch and the technology of microprocessor control AC stabilized voltage as an integral part of the whole. The power voltage stabilizers own the features of high efficiency, energy-saving, quick regulation, automatic balancing for three-phase, non-mechanical fault and non-wear to carbon brush, time-delay, and the functions of alarm and protection to over-and-under voltage, etc. Meanwhile, the power voltage stabilizers is the first to get rid of the common- mode current rush of contactless switch caused during the transient operation of system and equipment and the damage because of the over voltage. It is high in instantaneous overload, which greatly improve the reliability of system operation. PERFORMANCE Input voltage Single-phase 176-264V Three-phase 304~456V Wave form Distortion ≤2% Output voltage Single-phase 220V Three-phase 380V Frequency 50Hz/60Hz Stabilizing voltage precision ±2.5％ Power Factor ＞∣±0.7∣ Efficiency ＞95％ Instantaneous Overload function Instantaneous 1.5-2 times of rated load Adjust Time 0.2-0.5s Ambient temperature -15～40℃ Non-contacting, non-noises, and non-wear to machinery and carbon brush. 　 400KVA
