When you’re sharing laughter over dinner or drifting into a peaceful night’s sleep, your AC keeps the atmosphere just right and the V-Guard VSN 4140 keeps it protected. Built with care and precision, it ensures your family’s comfort remains safe from power fluctuations, so the moments that matter most stay uninterrupted.

Designed with precision engineering and powered by smart technology, this stabilizer ensures your AC always operates in its ideal voltage range, no matter how unstable the supply gets. Its advanced microcontroller-based circuitry offers superior speed and accuracy in voltage correction. Unlike traditional stabilizers, the VSN 4140’s intelligent system reads every variation and responds instantly, ensuring that your AC receives just the right amount of power consistently, safely, and efficiently.

And when power supply interruptions occur, the Intelligent Time Delay System (ITDS) steps in to prevent damage caused by frequent restarts. It automatically provides adequate rest time for the compressor before powering up again, maintaining your AC’s longevity and performance integrity. The Built-in Thermal Overload Protection ensures an added layer of defence. If your AC or other connected device consumes more current than it should due to internal faults or short circuits, the stabilizer quickly detects the overload and cuts off the supply. This protects both your appliance and the stabilizer itself from potential burnout.

The Low & High Voltage Cut-off Protection takes care of extreme conditions by automatically switching off when the input voltage moves beyond the safe operating range (140V–280V). This way, your air conditioner remains protected even in areas prone to severe power fluctuations.

Stay informed and in control with the Smart Digital Display, which clearly shows input and output voltages along with any active protection modes. It’s modern, user-friendly, and designed to keep you aware of what’s happening at a glance.

Encased in a durable wall-mountable metal body, the VSN 4140 is built not just to perform but also to complement your living space. Its slim, minimalistic design fits neatly alongside your air conditioner, adding a refined touch to your interiors. With a capacity of 12 Amps, compatibility for inverter ACs up to 1.5 tons, and a 3-year warranty, the VSN 4140 is an assurance of long-term protection, premium build quality, and complete peace of mind.

Thus VSN 4140 is a statement of superior technology, built to keep your comfort uninterrupted and your air conditioner performing at its peak, season after season.
