AULTEN Mainline Voltage Stabilizer for Home 3 KVA Heavy Duty 2400W 90V-300V AD012 (White)

Excellent product. Build quality and design also very good. No issues in using at home or office. Very user friendly and easy to install.

The media could not be loaded. I bought 5KVA mainline Stabilizer for my house, No step up is happening, even at 200volt, Worst product & and worst customer service at Aulten, .At least from Amazon please solve this problem.

Product Was really Amazing, its efficiency and affordability, this model is perfect for everyday household use.

Just adding one point if you are shifting to new location or buying lots of big electrical and electronics products at once instead of buying separate stabilizers for each of the item like Refrigerator, TV, Washing Machine etc., you can just buy this one for half the price and it's going to work like a charm.ORIGINAL REVIEW JULY, 2021:Overview, Warranty and Order :I live in sub-urban area and with such location comes severe electrical problems. Not only power outage for hours but also bad voltage fluctuation problem. I have been researching for a good stabilizer for whole house and Choice was between V-Guard and Aulten. I picked Aulten looking at reviews and speaking to customer care twice before purchase especially on warranty as I am in South India and manufacturer/seller is in Delhi. Once convinced that warranty will be taken care which is full replacement with Aulten borne transportation costs within 1 year of purchase without hassles I placed the order.Installation :Aulten does not provide installation. We need to get it installed ourselves (electrician or self). Although I am a Software Engineer I like DIY at home. So after reading product details in Amazon and product page and with my existing Electrical and electronics hobby knowledge I went for installation myself but not without dry run using my Iron box which was absolutely no hassle. Once dry run with iron box was successful I just connect input wires from mains, output wires to home mains and most importantly Earthing and powered on and it was running smoothly.Usage :I have Luminous UPS 1100, 900VA, 756 watts model which is most common in India. I just needed to connect stabilizer during mains on condition as the power fluctuations are very bad and hover around 170-270 volts throughout the day. But my load is only light load on 6 Amp line. I realised after purchase maybe I could have gone for 3KVA model as customer care suggested or even 2KVA model but nonetheless even if in future I upgrade my UPS this is still good. So if you are looking for UPS upto 4000 Watts this is still good for you.But... Problem :As few reviewers have already mentioned buy this ONLY if you have severe voltage variations throughout the day. DO NOT BUY if for most of the day you have voltage between 210-240 volts. There is a real problem of unusual buck and boost voltages as other reviewers have mentioned especially Mr. Devi's review. I have observed exact same voltage output problems when voltage is between 210-240 volts. For this I suggest company to upgrade circuit logic and add automatic bypass. This is extremely important so that when mains voltage is between 210-240 the stabilizer will just bypass. V-Guard stabilizer has this feature but it has other problems which is why I didn't buy that. But in case your voltage is outside of 210-240 most of the time then this is excellent choice.Conclusion :Excellent purchase overall despite few problems as mentioned above. I can recommend.

Easy to install and use. no issues faced for 6months use.

Very good product

The media could not be loaded. It does not do it's work of boosting the voltage properly. See the video of the problem. I spoke to the representative of the company, but till now no solution has been given. Overall service of the company is below standard.

Working fine after 2 years
