·         Q. What is an UPS and What it is for ?

An uninterruptible power supply (UPS) is a device that allows your computer or telephone switch or critical equipement to keep running for at least a short time or longer time when the primary power source is lost. It also provides protection from power surges, spikes, brownouts, interference and other unwanted problems on the supported equipment.

·         Q. How long the UPS to run when power goes?

This can take 3 paths.
1.You can pick a UPS that is rated for pretty much the full VA you need so it will be running at 100% of capability and will thus last 'n' minutes.
2.You can pick a UPS that is rated at a much higher VA value than you really need so, for example, is running at 50% of capability and will thus last for longer than the UPS from option 1.
3You can use extra external battery packs to run for longer. If charging capability allows, the more and the bigger batteries you take with, the longer time UPS runs. 
or using a generator after about 6 hours, it will be more cost-effective, with a short runtime UPS to bridge the generator start-up gap.
