SBW Series
Engineered for Nigerian power.
Every feature of the SBW-Series is designed around the realities of the Nigerian grid — extreme voltage swings, generator instability, and unpredictable outages.
01
Stepless Servo Regulation
A servo motor + toroidal transformer system delivers continuous, stepless voltage correction. No relay clicks, no jerks — just smooth regulation under any load.
02
Individual Phase Adjustment
Each of the three phases is corrected independently. Severe phase imbalance from NEPA or generators is compensated phase-by-phase for true balance.
03
Wide Input Range 304–456V
Whether the supply sags during peak demand or surges off-peak, the SBW handles a 152V swing without dropping output.
04
100% Copper Windings
Full copper transformer windings — never aluminium. Higher conductivity, lower heat, and a longer service life under continuous heavy loads.
05
LED / LCD Display
A multi-mode display combines a classic analog meter, a high-visibility LED panel, and a full LCD readout for live voltage and load data.
06
Uninterruptible Bypass
An integrated steering bypass keeps connected equipment online during maintenance. A mini bypass switch lets technicians service the unit without shutting down the line.
Pure copper. No compromises.
We refuse aluminium imitations. Every SBW transformer is wound with 100% copper — the gold standard for conductivity, heat resistance, and decades of reliable service under heavy industrial loads.
The full specification.
Available in 150 kVA and 200 kVA. Custom configurations on request.
