UPS - Backup Power Supply
An Uninterruptible power supply (UPS), also known as a battery
back-up, provides emergency power and, depending on the topology,
line regulation as well to connected equipment by supplying
power from a separate source when utility power is not available.
It differs from an auxiliary or emergency power system or standby
generator, which does not provide instant protection from a
momentary power interruption. A UPS, however, can be used to
provide uninterrupted power to equipment, typically for 5–15
minutes until an auxiliary power supply can be turned on, utility
power restored, or equipment safely shut down.
