General:
SBW/DBW Three-Phase/Single-Phase Independently-Regulating Stabilized Power Supply with fully-automatic compensation is a kind of modified SBW/DBW series product suitable for the electric network with unbalanced three-phase/single-phase voltage inputs. It can balance three-phase/single-phase outputs automatically and maintain the output in good condition during the fluctuation of electric network and load. Ideal Application: Post offices, stores, elevators, hospitals, schools, publishing houses, stock exchanges and other places where normal voltage is needed.
Use occasions
Widely used in posts and telecommunications, shopping malls, elevators, hospitals, schools, printing, textiles, securities and other occasions where normal voltage is required, as well as large and medium-sized industrial and mining enterprise workshops, some power supplies and important equipment and accessories.
