How to calculate UPS time ?
(OP)
For UPS with batteries packs of 5000 VA.
How much the UPS will last for:
1- A PC that consume 280 Watts
2- An instrument that consume 36 Watts

Anything more than that will take a lot more information about your UPS.

5000VA would be the rating of the UPS and UPS info is irrelevant.

RE: How to calculate UPS time ?
But... the question you need to find out is, how long can the UPS do that? 10min, 30min, etc... That is the energy content.
You say have two loads at a total of 316W. (Assuming they both run continously and at the same time). If you want them to run for an hour, you'll need 316Wh of capacity.
So say you have a battery that is at 12V and say it can discharge 30Ah till "some voltage." That's 360AH. You will have roughly (a ballpark, I didn't account for the UPS efficiency,etc) 1hour and 8 minutes worth of runtime.
Hope that helps.
