APPLICATION
SBW-F series three-phase sub-regulation full automatic compensation power voltage regulator is a new voltage regulator improved based at SBW series products, which is suitable for unbalanced three-phase input voltage grid. When the load current changes or fluctuations in power grids, three-phase output automatically balance, and keep the merits of a steady voltage regulator

USE SITUATION
Widely used in post and telecommunications, department stores, elevators, hospitals, schools, printing, securities and other occasions where all needs normal voltage to ensure, such as workshop mines medium enterprises, some of the important equipment and computer power and support.
