UPS එකකින් power backup එකක්

650VA UPS එකකින් Full charge කරලා 9W බල්බ් එකක් කොයි කරම් වෙලාවක් දල්වන්න පුලුවනි ද? ගණනය කර ගන්න විදිය පැහැදිලි කරන්න. Thanks.

10W flasher ekak 1.5H wage weda karanawa .... ups eke battery yath dan tikak paranayi....aluth ekakin 3H wage puluwan weyi

Battery Wh / (bulb power*20%) (20% of loss in conversion)


Battery used in regular 500-650VA ups is 7Ah 12V = 84Wh


so, 84/(9w*20%) = 7.7 Hours


But in real life, will last 5 hours
