Dear All,

I want to know the UPS (kVA) sizing calculation, based on

a) Connected load

b) Average operating load

c) Peak load with duration.

Is any web site or formula is available.

Apart from reading other similar posts.

Work out your Maximum Demand for the circuits being supported by the UPS....

Then read the Technical specs of UPSs you are interested in buying and compare them with your requirements from step 1.

Regards,
Sapper
