What is d diff. btw Online & Offline UPS???..

Answer / abanikanta

Besides above mentioned answer (1) I would like to explain some points--
1)Using a online UPS is advantageous for us because of interruption of line supply.As mentioned after main supply fail we use power from battery...........this is a problem :the time it takes to changeover .for example,if our system is much sensitive we may get interruption in getting supply. Normally the the change over time is in order of few millisec.

2) Online UPS is observed to be more economical for higher rated UPS.
