This UPS has an intelligent? (dumb) load detecting circuit, which shuts down the UPS when there is no load connected to it. In majority of the cases, this stupid circuit wont detect a load (in this case the computer) even if there is a load and it just shut down itself. So the UPS goes into off mode within 20 seconds after the main supply is lost.
then how many hours required to be charged for the ups in old condition to stay back the pc for 15-20 mins
when the current flops?
pls...giv me the answer...
