Industrial Systems
Heavy three-phase servo stabilizers — built for factories that cannot lose a single shift.
Made for three shifts a day.
Each phase is corrected on its own, so an unbalanced WAPDA supply becomes clean, balanced 400 V. It uses heavy copper, big contactors and forced cooling that runs all day.
Control & metering
Shows voltage and load for each phase.
Forced-air cooling
Runs all day at 50 °C.
Heavy busbars
Big copper for hundreds of amps.
Steel enclosure
Floor-standing cabinet, ready for bypass.
Each phase, corrected on its own.
Three servo systems, one per phase, drive stepless autotransformers. A lopsided incoming supply becomes a clean, balanced output. IGBT models do the same with no moving parts.
Per-phase correction
Unbalanced input becomes balanced 400 V on all three phases.
Heavy copper path
Big windings and contactors carry the full industrial current.
Continuous 50 °C duty
Forced cooling and heat protection for 24/7 running.
Bypass & monitoring
Bypass cabinets and remote monitoring keep production going.
Across Pakistan's industry.
Textile mills
Keeps looms and motor drives safe from voltage swings across Punjab.
Food & poultry
Keeps grinders and cold rooms running, as at K&N's Kasur plant.
Cold storage
Steadies compressor loads to stop costly motor burnout.
Commercial buildings
Whole-building correction for malls, hospitals and offices.
Uptime, built in.
Balanced output
Each phase fixed to a clean 400 V ±1%.
Deep low-V correction
Holds output even when input drops to 260 V L-L.
24/7 duty cycle
Runs all day at 50 °C, three shifts a day.
Oversized contactors
Heavy copper and contacts take surge and inrush.
Service contract
Planned engineer visits keep the plant protected.
Remote monitoring
Check voltage and load from your phone, anywhere.
Five layers of protection.
Every unit watches the grid and shuts the load out of harm automatically — no manual reset, no babysitting.
Overload protection
Trips the moment the connected load draws more than its rated current.
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.
