● Servo Voltage Stabilizer · Single-Phase · Wall-Mount

The TSD Series. Stable power. No floor space required.

A compact, wall-mounted single-phase voltage regulator with servo motor precision. Accepts 90–260V AC and delivers a steady 220V ±2% — protecting every appliance in the room without taking up any floor space.

TSD Series

Core Features

Smart protection in a compact wall package.

The TSD takes everything you need in a voltage stabilizer and puts it in a wall-mounted format, saving floor space without sacrificing performance.

Wall-Mount Design

Installs directly on the wall, freeing up valuable floor and shelf space. Ideal for compact homes, apartments, offices, and server rooms where a vertical floor unit would be impractical.

Ultra-Wide Input: 90–260V

Handles the full extremes of Nigerian grid instability. Even when input drops to 90V, the TSD continues delivering stable 220V output — critical in areas with chronic under-voltage.

Servo Motor + Toroidal Transformer

Stepless, continuous voltage regulation with no relay switching gaps. The servo motor and toroidal transformer combination delivers the smoothest, most precise regulation available in a compact stabilizer.

Informative LED Display

A real-time LED display shows input voltage, output voltage, and system status at a glance — visible from across the room, no external monitoring required.

100% Copper Transformer

Full copper windings deliver lower heat generation, superior conductivity, and a significantly longer service life — even under continuous heavy load in hot, humid environments.

Real Output at Low Voltage

The 5 kVA model delivers 2,300W and the 10 kVA model delivers 4,800W even when input drops to 90V — keeping your appliances powered through the most severe brownouts.

Pure copper. No compromises.

We refuse aluminium imitations. Even at this size, every TSD is wound with 100% copper — the gold standard for conductivity, heat resistance, and decades of reliable service under continuous loads.
