Feature | SBW-F adjustable automatic compensation power voltage regulator is
a new voltage regulator improved based at SBW series products,
which is suitable for unbalanced three-phase output automatically
balance, and keep the merits of a steady voltage regulator.It is
composed of three sets of single-phase voltage stabilizer
by"star-shaped" connection. With the function of three phase
independently voltage-stabilizing, it applies to the unbalanced
input voltage of three phases or unbalanced three phase loads.
Moreover, it has the functions such as voltage regulating
stability,high voltage stabilizing precision, and autobalance of
three phases. The regulating voltage parts of this series voltage
stabilizer is adopted the pillar. There fore, it has more power and
more reliability. | | Application | Widely used in post and telecommunications,department stores,
elevators, hospitals,schools, printing, securities and other
occasions where all need normal voltage to ensure,such as workshop
mines enterprises,some of the important equipment and computer
power and support. |
