V-Guard VG 400 for 1.5 Ton A.C (170V to 270V) Original 3 Year onsite wrranty,GREY

Correct product

product is very good and also reliable product V guard and durability and long time working but I receive this product warranty seal is broken

I installed the V-Guard VG 400 stabilizer for my 1.5-ton air conditioner in an area where voltage fluctuation is common, especially at night. After installing it, the AC compressor started operating normally and cooling performance improved. The stabilizer supports a 170V–270V input working range, which is suitable for most homes with moderate voltage fluctuation. It uses advanced IC-based circuitry to regulate voltage and provide a stable output for sensitive components like the AC compressor and PCB. Another useful feature is the Intelligent Time Delay System (ITDS), which delays the compressor restart after a power cut. This protects the compressor from damage caused by sudden power restoration. Technical Points - Working voltage range: 170V – 270V - Capacity: 12A, suitable for AC up to 1.5 Ton - ITDS compressor protection (~3-minute delay) - Thermal overload protection - Compact wall-mount ABS cabinet - 3-year warranty Pros - Stable cooling after installation - Good protection against voltage fluctuation - Reliable brand and build quality - Easy installation Cons - No digital voltage display - Slight restart delay after power cuts (normal due to ITDS) Overall: A dependable stabilizer for protecting a 1.5-ton AC in areas with unstable voltage supply. Good value for long-term compressor safety.

The company claims an operating range of 170V to 270V on paper, but the reality is entirely different. This stabilizer consistently trips at 262V, falling well short of its advertised upper limit. This is a massive red flag, especially if you live in a locality with grid-tied rooftop solar setups. In my area, daytime grid voltage naturally idles around 250V and easily spikes to 285V when the neighborhood load is low. Even during peak afternoon hours with multiple ACs running in the area, the voltage hovers around 260V to 263V. Because this stabilizer cannot handle anything past 262V, it constantly cuts power, leaving the AC useless exactly when you need it most. Attempting to get this resolved or calibrated via customer care was a frustrating loop. The frontline support couldn't grasp the technical issue. When a service engineer finally visited, he tried to justify the premature tripping by claiming a "2.5% accuracy margin" on the 270V limit (which would technically mean a trip range of 263.25V to 276.75V). Even by his own flawed math, my unit tripping at 262V proves the product is simply underperforming and defective by design. The Bottom Line: If your house's baseline voltage is around 250V, this model only gives you a useless 10V regulation window before shutting down. Constant tripping doesn't protect your AC; it actively damages the compressor through short cycling. If you have a solar PV system at home or in your neighborhood, absolutely skip this and buy a stabilizer with a much higher upper-voltage tolerance.

Good product

V guard VG 400 good.

Very very nice product and quality is great and best best best work
