UPSs are sued not just in software companies, but in many
other firms, where continuity of electric power is critical
for operations. UPS (Uninterruptable Power Supply), is an
device that works on batteries with associated electric
circuitry to ensure the power supply is uninterrupted in
the event of primary electric power supply is disrupted for
some reason. Since, power outages are common in India, the
usage of UPS or inverter (mostly found in Indian homes)is
quite common in india to ensure uninterrupted power supply.
However, the capacity of UPS is specified in number of
hours it can provide certain rated power.
