Correction speed

Proven & popular

The servo stabilizer built to last.

Heavy copper windings, big contacts and a powder-coated steel cabinet — sized to keep your ACs, fridge and electronics safe through Pakistan's sags and surges.

Voltage & load display

Shows live input, output and load.

Servo motor drive

Motor moves a slider for smooth correction.

Copper windings

Smooth, stepless autotransformer.

Steel cabinet

Powder-coated and heat-protected.

How it works

Smooth, continuous correction.

A servo motor moves a carbon-brush slider across a stepless autotransformer. It fixes voltage in a smooth sweep, not the harsh jumps of a cheap relay unit.

Motorised slider

A servo motor moves a carbon brush along the winding to hold exactly 220 V.

Continuously variable

No fixed taps, so correction is smooth and your AC compressor never gets a jolt.

Real copper autotransformer

Heavy copper windings and big contacts carry the full load without sagging.

Thermal-protected control

A controller proven in Pakistani homes and shops for over 15 years.

Where it fits

Sized for homes and shops.

One or two AC homes

5–10 kVA covers one inverter AC, or two ACs plus the rest of the house.

Whole-home protection

15 kVA holds geyser, motors, ACs and electronics on one clean supply.

Shops & small offices

Keeps tills, lights and fridges steady through evening voltage drops.

Motor-driven appliances

Smooth correction keeps compressors, pumps and washing machines safe.

Key advantages

The servo done right.

Smooth correction

A smooth sweep, not stepped jumps, so it is easy on compressors.

±1% output accuracy

Holds voltage tight across the full input range.

Wide 140–280 V input

Keeps working when evening voltage drops far.

Voltage + load display

Dual LED / LCD screen shows live status.

Copper, not aluminium

Real copper windings and big contacts for the full load.

Service you can reach

Backed by our own service network — the strongest in the market.

Built-in safety

Four layers of protection.

Every unit watches the grid and shuts the load out of harm automatically — no manual reset, no babysitting.

Over-voltage protection

Cuts the output the instant mains voltage spikes dangerously high.

Under-voltage protection

Disconnects the load when the supply sags below a safe level.

Over-temperature cut-off

Shuts down on excess internal heat, then resumes once it cools.

Short-circuit protection

Isolates the output instantly if a short circuit is detected.

Common questions

Questions, answered.

What size servo (SVC) stabilizer do I need for my home?

Add up your load. One inverter AC plus a fridge and lights is about 5 kVA. Two ACs and the rest of the house is about 10 kVA. A full home with a geyser, motors and two–three ACs needs 15 kVA. If you are not sure, send us your appliance list on WhatsApp and we will size it for you.

Is a servo (SVC) stabilizer better than a relay (AVR) one?

For whole-home use, yes. A servo stabilizer corrects voltage smoothly and holds a tight ±1%, while a relay AVR jumps in steps of ±5–10%. The smooth correction is much easier on AC compressors, fridges and motors, and it covers a wider input range.

Should I buy a servo (SVC) or an inverter (IGBT) stabilizer?

For most homes and shops, the servo (SVC) is the proven, value choice and handles motor loads well. Choose the inverter (IGBT) if you run sensitive or precision equipment — laser, CNC, medical or lab gear — that needs instant 0 ms correction and a perfectly clean pure sine, or if you want silent, maintenance-free operation.

Does a servo stabilizer need maintenance?

A little. It uses a motor and a carbon brush that move a slider across the winding, so the brush wears slowly over years and can be replaced. We service what we sell — our network is the strongest in the market.

What input voltage range does it work in?

The Voltec SVC servo range holds a steady 220 V output across a wide 140–280 V input, so it keeps working through Pakistan's evening voltage drops and surges.

Do you deliver across Pakistan, and do you export?
