SBW-F Three-phase Separately-regulating Electric Voltage Stabilizer, Fully-automatic & Compensated Type is a kind of modified SBW series product suitable for the electric network with unbalanced three-phase voltage input. It can balance three-phase output automatically and keep the network operating in good condition during fluctuation of electrified wire netting and transformation of load current.


Widely used in the fields of post office, store, elevator, hospital, school, publishing house and stock exchange where normal voltage is in need, and also can be used in the factories of large and middle-scale industrial and mining corp. It is very much suitable for some important devices and supporting single machine.
