Servo Voltage Stabilizer
THREE-PHASE SBW Series
Nigeria’s toughest power challenge, met head-on. The SBW-Series automatically corrects voltage from 304–456V AC to a rock-steady 380V output — protecting every appliance in your home, office, or factory.
Core Features
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.
Stepless Servo Regulation
Unlike step-type relay stabilizers, the SBW-Series uses a servo motor + toroidal transformer system for continuous, stepless voltage correction. No steps, no jerks — just smooth, uninterrupted regulation at all times.
Individual Phase Adjustment
Each of the three phases is adjusted independently. Even when your supply has severe three-phase imbalance — common with NEPA and many generators in Nigeria — the SBW compensates each phase separately for true balance.
Wide Input Range 304–456V
Accepts an input range of 304–456V AC. Whether your incoming supply sags dramatically during peak demand or surges dangerously during off-peak hours, the SBW-Series handles it without blinking.
100% Copper Windings
Full copper transformer windings — not aluminium imitations. Copper delivers superior conductivity, lower heat generation, and a significantly longer service life under the continuous heavy loads typical in Nigerian operations.
LED / LCD Display
The unit features a multi-mode display that provides everything you need in one view. It seamlessly integrates a classic analog meter for quick checks, a high-visibility LED panel for status updates, and a full LCD for detailed, real-time voltage and load data.
Uninterruptible Bypass
Built-in uninterruptible steering bypass means you can maintain power to connected equipment even during maintenance or fault conditions. A mini bypass switch lets service technicians work without shutting down your operation.
Protects Every Industry
From homes to hospitals, the SBW-Series delivers stable three-phase power wherever Nigerian voltage is a threat.
