Unstable mains voltage shortens equipment life, trips machines and corrupts sensitive electronics. Prince PowerTech supplies and installs automatic voltage regulators that continuously sense the incoming supply and correct it to a stable, safe output. From selecting the right type and capacity to installation and after-sales service, we deliver the complete solution.
We match the technology to your voltage profile, load size and budget — then back it with built-in protection you can rely on.
A motor-driven variac gives precise ±1% regulation over a wide input range — ideal for industrial loads and slow, deep fluctuation.
Thyristor / IGBT based with no moving parts — extremely fast correction (in milliseconds) for sensitive electronics and IT loads.
An economical step-correction stabilizer for homes, shops and small equipment where budget matters and loads are modest.
Holds output at 220/230 V ±1% (single-phase) or 400 V (three-phase) regardless of input swings.
Corrects a broad input band (typically 140–480 V, configurable) so even severe fluctuation is handled.
Servo units track continuously; static units correct in milliseconds — no interruption to your process.
Shields motors, drives, medical and IT equipment from spikes, sags and burnout — extending their life.
Above 95% efficiency means minimal losses and lower running cost, even at continuous full load.
On-board digital meters show input, output and load — with clear indicators and fault status.

An AVR constantly senses the incoming voltage and adjusts to deliver a clean, stable output. Your machines see steady power even when the grid rises and falls — preventing trips, resets and long-term damage.
We survey your load and voltage profile first, so you get the correct type and capacity — never over- or under-sized.
Stabilizers with genuine components, proper testing and calibration before handover.
Skilled engineers who install, calibrate and service voltage stabilizers across many industries.
Corporate office in Uttara, Dhaka and a branch in Jamalpur — with support teams across Bangladesh.
Clear warranty terms and ready availability of spare parts keep your equipment protected long-term.
Round-the-clock breakdown response and annual maintenance contracts (AMC).
