I am a Microtek UPS user for past 4 years. I was using Microtek SEBz850 850VA UPS before buying this UPS, I bought this UPS ( along with Exide 200Ah Tubuler Battery) from local dealer. The product is good without those fancy LCD display or temperature sensor. Believe me those terms are nothing but marketing gimmick and increase the cost price of the product. This microtek ups has minimalist features like input voltage selector ( 100-300 or 180-260) , battery voltage selector ( ’High’ for Tubuler and ’Low’ for SMF) and Battery current selector ( ’High’ for battery with capacity of 150Ah & above and ’Low’ for battery with capacity of 135Ah & below, though it is not recommended to use battery with capacity bellow 150Ah) . Some company like Su-Kam/Luminous ups has feature like charging capability at voltage as low as 85-90VAC unlike microtek ups which goes into battery mode at that voltage. Don’t fall for that, no doubt it is good feature but it is also true that no electronic product runs at voltage below 100VAC, so if you want to run any electronic product at voltage lower than 100VAC you need a voltage stabilizer. It means even if your ups is capable of charging battery at very low voltage ( 85-90) you still need a voltage stabilizer to run other electronic items.
