if my 6 kva UPS gives 20 min. backup at 100 % load, then at
25% load what is the backup time?

Answer Posted / prakash kusuma

at 25% load a 6kva UPS give back up of 50 min
as at 100% = 20 min ok
50% = 40 min
25% = 50 min (40 min + 20 min = 60 min(no load)
- 10 min(25 % load )= 50 min( back up)

Is This Answer Correct ?    1 Yes 0 No
