Online UPS alwaws given Constant voltage i.e.230V 50 Hz.and
what ever input like 170 v to 270V.Voltage goes through the
circuit and through the Battery in any time when AC is
present or on Backup position.
Offline UPS alwaws gives Same output what is input received
from Main. Voltage goes Without Circuit and only Battery
charging Voltage 12V DC goes to battery.When Mains is fail
then supply goes from battery backup.
Resultant On Line UPS Costly than the OFF Line UPS.
