TNS Series

Core Features

Three-phase precision for Nigerian power.

The TNS combines servo motor speed with toroidal transformer accuracy, delivering reliable three-phase voltage stabilization across the full range of Nigerian grid conditions.

01

260–490V Wide Input

Handles the full spread of Nigerian three-phase supply instability. Whether your incoming voltage sags to 260V at peak demand or surges to 490V off-peak, the TNS regulates it continuously to 380V, without manual intervention.

02

Stepless Servo Motor Control

A servo motor and toroidal transformer system eliminates the discrete relay steps that cause micro-interruptions. Correction is smooth and seamless, critical for sensitive equipment like inverters, CNC machines, and medical devices.

03

100% Copper Windings

Every TNS uses 100% copper transformer windings, delivering superior conductivity, lower heat generation, and a longer service life than aluminium alternatives. Built to run continuously in industrial environments.

04

Informative LED Display

The LED panel shows real-time input voltage, output voltage, and system status. At a glance, operators can verify the stabilizer is actively protecting the load no external monitoring required.

05

Thermal Protection

 Continuous winding temperature monitoring keeps the transformer below 85°C under full load. Thermal protection activates before insulation degradation can occur extending service life in hot, humid environments.

06

Four Capacity Models

Available in 20, 30, 50, and 100 kVA configurations. Whether you’re protecting an office building, a factory floor, a telecom site, or a large commercial complex, there’s a TNS sized to your load.

TNS Series 3 Phase Servo Voltage Stabilizer (260–490V AC)

Pure copper. No compromises.

We refuse aluminium imitations. Every TNS transformer is wound with 100% copper, the gold standard for conductivity, heat resistance, and decades of reliable service under continuous loads.
