 SBW/DBW Automatic compensated power voltage stabilizer


This is product is designed and developed with the international advanced compensation technology.It can keep the output voltage in steady state automatically when the network voltage fluctuated or the load current c=varied,which can ensure the consumer run smoothhly.It has the advantage of large capacity ,high efficiency ,no waveform distortion,simple operation  and maintenance ,reliable running ,full-capacity output under tower input voltage if compared with other voltage stabilizer.It is provided with over- voltage ,over-current,phase sequence and so on protection function.

Scope of application

It is suitable for electric supply in small-sized plant,workshop and department inmiddle,large-size  mining enterprise,it can be widely used in the precision machine tool,precision instrument ,test device,elevator,imported electromechanical device,production flow-line in the mining enterprise, oil field ,railway,building site,school,hospital,hotel,,scientificresearch department and so on,it is also suitable for the user in the LV electric network end with low power voltage and bog wave range.
