Detailed Description
We develop DBW/SBW (single-phase/three-phase) series high power compensation voltage stabilizer under our experiences in conjunction with the high technology from West Europe. While the voltage fluctuates because of the fluctuation of outside network voltage or loading change, it is used for stabilize the output voltage. Compared with other model of voltage stabilizer, this series includes the advantages as big capacity, high efficiency, no waveform distortion, stable voltage adjustment, large applicable loading, bearing ing instantaneous overload, long continuous working, switch for manual & automatic operation, protection against overpressure, phase loss and other mechanical failure, small size, light weight, easy to install and reliable operation, etc. It has come into widely used in transportation, post and telecommunication, Broadcast and T.V, computer system, Printing, Numerically controlled machine tool. Main Technical Specification 1 Input Voltage 3 PH + N 380 VAC 2 Input Voltage range ± 20% ( from 304 VAC to 456 VAC ) 3 Output Voltage 3PH + 380 VAC RMS stabilized 4 Output Voltage Accuracy ± 1 %~± 5 % Adjustable 5 Frequency 50/ 60 Hz ± 5% 6 Admitted Load Variation 0 to 100% 7 Admitted Load Unbalance Up to 100% 8 Response speed Within 1.5sec as input voltage vary 10% 9 Wave form distortion NO ADDITIONAL WAVEFORM DISTROTION  10 Efficiency > 95% (Power grand is higher than 50KVA) 11 Cooling Free Convection 12 Ambient Temperature - 10℃ to + 50℃ 13 Storage Temperature - 20℃ to + 60℃ 14 Relative Humidity 90% (without condensate) 15 Load Power Factor 0.8 16 Overloading capacity 2 times of rated electric current within 1 minute 17 Instruments Voltmeter with selector to read input- output voltage (phase to phase ) pilot lamps input/ output terminal, 18 Withstand voltage 1500V AC/1Min
