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.
