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 equipment to keep running for at least a short time or longer time when the primary power source is lost. It also provides protections 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.
3.You 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.

Q. What’s lifetime of a UPS ?

Most plug-in UPS are workable for at least five years. We’d advise you to change the batteries every three to four years. For larger equipment, we maintain equipment for twenty years old and still going strong.

Q. How to maintain a UPS ?

There are three simple methods: Never overload your UPS, never connect any home electronic devices such as cooling fan to your UPS. This may cause malfunction of your UPS. Discharge the battery in a consistent interval, once a month or once two months. You can do this by turning on the UPS without connecting the mains.

Other regular preventative maintenance work:
Environmental checks
Electro-mechanical checks
UPS functional testing
Battery Assessment
Most batteries have a life expectancy of between 3 and 5 years, so it is vital to check the condition of your UPS batteries on a regular basis.
