V-Guard iD4 Ace 5540 AC Stabilizer for 1.5 ton Inverter AC | Digital Display with Colour Changing LED Rings | Intelligent Time Delay System| 3 Year Warranty | White (Working Range 130-280 VAC)

I recently purchased the V-Guard iD4 Ace 5540 AC Stabilizer for my 1.5-ton inverter AC, and I must say, it’s been an outstanding investment! The stabilizer is sleek and compact, and it does a fantastic job of keeping the voltage steady, which is essential for my AC's performance. The design is modern, and it’s built to last with high-quality materials. I’ve noticed a significant improvement in the efficiency of my AC since using this stabilizer. It protects the unit from voltage fluctuations and ensures smooth operation. The stabilizer is also very quiet, which is a bonus. Installation was easy, and the device works flawlessly without any issues. I highly recommend this stabilizer to anyone looking to protect their AC and improve its longevity. V-Guard has truly delivered with this product. Worth every penny!

All the features of this stabilizer are good it works silently and efficiently. The only thing is the LED, which dims a bit, but on the bright side (pun intended), it still doubles as a night light, so you won’t need a torch. Just wish they had given an option to turn off the LED light.

Product is good, but packing is not good. Scratches are there

I recently installed the V-Guard iD4 Ace 5540 for my 1.5-ton inverter AC, and the performance has been flawless. Living in an area with frequent voltage shifts, I needed something that could handle a wide range, and this stabilizer's 130V-280V working window is perfect. The build quality is solid, and the digital display is a standout feature—the color-changing LED rings (Blue for normal, Red for cut-off) make it very easy to monitor status at a glance. It operates silently and the 'Intelligent Time Delay' gives me peace of mind regarding compressor safety. If you own a premium inverter AC, this is a must-have investment for longevity.

This product comes highly recommended for all users, particularly those with a 1.5-ton air conditioner. It performs exceptionally well without any problems, boasts an attractive design, offers excellent features, and provides good value for the price. The display is also quite pleasing.

Good product

This will stopped working within 6 months. I’m really disappointed with this product and service from V guard customer service team. I have raised the complaint to Service team on 21st march and crossed 21 days. Still I’m not getting any response from Service team. I don’t know when I may get a solution. Strongly Not recommended to this brand.

Purchased it for 1.5 Ton Split Inverter AC (working Range 130-280 VAC). Timely delivered and Packaging is good condition. It is look very nice and review after one month it works accurately and efficiently with the input voltage and output i.e. performance was as expected. Display of voltage is in blue is good, but at the time of sleep this display blue light is too much bright in the dark bedroom. No noise issue, value for money. Overall, this product is very good.
