Answer Posted / venkatraman
An off-line UPS remains idle until a power failure occurs,
and then switches from utility power to its own power
source, almost instantaneously. An on-line UPS continuously
powers the protected load from its reserves (usually lead-
acid batteries or stored kinetic energy), while
simultaneously replenishing the reserves from the AC power.
The on-line type of UPS, in addition to providing
protection against complete failure of the utility supply,
provides protection against all common power problems, and
for this reason it is also known as a power conditioner and
a line conditioner.
