An air conditioner is the most voltage-sensitive thing most Delhi homes own, and June is when the grid is least willing to cooperate. The evening the whole colony's compressors kick in together, the line sags; the moment supply returns after a cut, it spikes. A 1.5 Ton AC caught in either condition is asking its compressor and its control board to work outside what they were designed for, and that is how a five-year-old AC becomes a repair bill. This Logicstat covers the whole band from 145V right up to 280V — one of the widest windows you will find on a domestic stabilizer — and holds a corrected output through all of it, so the AC runs on clean power on the worst night of the summer.
Microcontroller-based digital AVR with zero-crossing detection
The difference between an ordinary stabilizer and this one is how fast and how cleanly it makes each correction. A microcontroller monitors the incoming supply continuously and drives the digital automatic voltage regulator, so correction is quick and the output stays consistent rather than lurching in steps you can hear through the AC. Zero-crossing detection is the refinement behind it: switching is timed to the instant the AC waveform passes through zero, which means almost no arcing across the relay contacts. That does two things — it extends relay life substantially, and it is why the unit runs quietly instead of announcing every correction with a loud click. Combined with the digital display showing live voltage on the front, you can see exactly what the grid is doing and what your AC is actually receiving.
Copper wound, thermally protected — built for a 50°C Delhi afternoon
The transformer inside is copper wound, and that choice shows up in two places you care about: higher electrical efficiency, so less of your power is lost on the way to the AC, and lower heat generation, so the unit runs cooler and lasts longer. Heat is what kills stabilizers, and a stabilizer sitting on a wall in a Delhi flat in May is working in a hard environment. This one is rated to operate from 10°C to 50°C and carries built-in thermal protection and cooling, so it stays safe through the extremes at both ends of the year. Add High-Low Voltage Cut-Off, which shuts the supply off entirely when voltage goes beyond safe limits, and your AC is protected even in the conditions no stabilizer should try to correct through.
🛡️ Four layers of protection working together
HLC Cut-Off
Cuts the supply automatically during unsafe high or low voltage
Digital Display
Real-time voltage on the front panel, so you can see the grid
Silent Operation
Premium electromagnetic relays work without loud clicking
Zero-Crossing
Switching timed for longer relay life and better accuracy

Copper Wound
Higher efficiency and lower heat generation for a longer life
Microcontroller AVR
Faster response and consistent, precise output voltage
Thermal Protection
Built-in protection and cooling for safe running in extreme climates
Compact & Stylish
Sleek, space-conscious design that suits any room
🔧 What you get with it
The live voltage display is the feature customers end up appreciating most — you stop guessing about your supply and start seeing it.
Rated specifically for air conditioners up to 1.5 Ton, so it carries the compressor's start-up surge as comfortably as its running load rather than sitting at its own limit.
Copper windings raise electrical efficiency and lower heat generation — the two things that decide both what a stabilizer costs you to run and how many summers it survives.
When the supply goes beyond what can be safely corrected, HLC disconnects the AC entirely instead of passing damaging voltage through to the compressor and PCB.
Two full years of Logicstat cover with service at your doorstep — no dismounting the unit and carrying it to a service centre in the middle of the cooling season.
