Voltage Regulation, engineered
to hold steady under any load.
Terravolt's voltage stabilizers protect your equipment from fluctuating mains supply — a compact air-cooled unit for homes and offices, and a heavy-duty oil-cooled platform for industrial and high-load installations — with remote monitoring so you always know exactly where your output voltage stands.
Regulating Live
Choose the cooling type that fits your load.
Two voltage stabilizer types — air-cooled for everyday loads, oil-cooled for heavy industrial demand.
Residential & CommercialAir Cooled Voltage Stabilizer
Ideal for homes, offices and light commercial loads — fan-assisted cooling for reliable regulation with zero oil maintenance.
- 5–100kVA Power Range
- ±1% Accuracy
- IP54 Enclosure
Industrial & Heavy DutyOil Cooled Voltage Stabilizer
Built for factories and heavy inductive loads — oil-immersed cooling for continuous, high-capacity operation.
- 100–2000kVA Power Range
- ±1% Accuracy
- 24/7 Duty Cycle
Air Cooled Voltage Stabilizer
Designed for homes, apartments, offices and small commercial sites where moderate load protection is required. Uses forced-air cooling to regulate output voltage without the added weight, footprint or maintenance of an oil-filled unit, making it the most common choice for everyday installations.
- Best suited for household appliances, offices and retail loads
- Compact footprint — no oil top-up or draining required
- Fast servo or relay-based correction response
- Wall-mounted or floor-standing options available
Oil Cooled Voltage Stabilizer
Built for industrial plants, manufacturing lines and sites running heavy inductive or continuous-duty loads. The oil-immersed design dissipates heat far more efficiently than air, allowing the unit to handle higher capacities and sustained operation without derating.
- Ideal for factories, process plants and large motor loads
- Superior heat dissipation for continuous 24/7 operation
- Longer service life under sustained high-current conditions
- Scalable up to large kVA ratings for whole-site protection
Everything your equipment needs to stay protected — nothing it doesn't.
Wide Correction Range
Corrects input fluctuations from as low as 150V up to 270V, delivering a stable output your equipment can rely on.
Rugged, Weatherproof Build
Powder-coated steel enclosure rated for indoor and outdoor installation, built to handle dust, humidity and heat.
Remote Monitoring
Track output voltage, load and fault history remotely, with alerts pushed straight to your phone or dashboard.
Digital Voltage & Current Display
A clear front panel display shows real-time input/output voltage and load percentage at a glance.
Multi-Stage Protection
Built-in overvoltage, undervoltage, overload and short-circuit protection safeguards connected equipment automatically.
Fast Correction Response
Servo or relay-based correction reacts within milliseconds, so sensitive electronics never feel the fluctuation.
Built to a standard, not just a spec.
Live in four steps.
Load Assessment
We evaluate your connected load, incoming voltage range and site conditions to size the right stabilizer, air or oil cooled.
Installation & Wiring
A certified electrician positions the unit and wires it into your incoming supply and distribution board.
Calibration & Testing
Output voltage is calibrated to your equipment's requirement and tested across the full expected input range.
Commissioning & Handover
The unit is switched live, monitored through a settling period, and handed over with a start-up report.
Every angle, every detail.
