On a June evening in Delhi, when every AC in the colony switches on at once, the line voltage at your socket can sag to levels your air conditioner was never designed to run on. This Logicstat holds a working window from 170V all the way up to 270V — the deep evening sag and the late-night surge both sit comfortably inside its range. Instead of your compressor struggling on starved voltage or taking a hit from an overshoot, the stabilizer corrects the supply and hands the AC a clean, steady feed. That single band, 170V to 270V, is what stands between a Delhi power line and the most expensive component in your air conditioner.
Advanced Microcontroller + Digital Signal Processing — correction with real precision
An older relay stabilizer reacts in coarse jumps; a digital one thinks first. Logicstat builds this unit on an advanced microcontroller circuit with Digital Signal Processing, so the incoming supply is measured continuously and the correction applied is the precise one — high-accuracy output rather than an approximate step. Zero-Crossing Technology times every relay switch to the exact moment the AC waveform crosses zero, which is why the transitions are smooth, the relay contacts last far longer, and there is none of the thumping you associate with cheap stabilizers. High-quality electromagnetic relays keep the whole operation silent — it sits in your bedroom corridor and you forget it is working.
Copper wound, vacuum transformer, built for Delhi heat and dust
The transformer is the heart of a stabilizer and this one is copper wound with an energy-efficient vacuum-impregnated build — lower losses in normal running, and the mechanical solidity to keep tolerances stable over years of switching. A robust cooling design keeps internal temperatures inside safe limits even through a 45°C afternoon on a west-facing wall, and the unit is rated to operate anywhere from 10°C to 50°C ambient — the full spread of a Delhi NCR year, from a January morning to the peak of a loo-wind June. The body is finished to sit neatly on a modern wall instead of looking like site equipment.
🛡️ How your AC is protected, step by step
Continuous Sensing
Microcontroller circuit reads the incoming supply in real time
170V–270V Correction
Sag or surge inside the band is corrected to a stable output
Zero-Crossing Switching
Relays change at the zero point — smooth, silent, longer life
High-Low Cut-Off
Beyond safe limits the supply is cut so the AC is never exposed
🛠️ What is engineered in
The digital display is the one you will use daily — a glance tells you exactly what the line is giving you and what your AC is actually receiving.
The compressor and control board are the costliest parts of an air conditioner and the first to suffer from unstable supply. This stabilizer stands between them and the mains, so voltage swings hit the stabilizer instead of your AC.
The microcontroller-driven design and energy-efficient vacuum transformer keep internal losses low, so the protection you have added does not show up as a meaningful line on your electricity bill.
Rated for 10°C to 50°C ambient with a robust cooling design — built to keep working through peak Delhi summer, monsoon humidity and the dust that settles on everything in this city.
