Background
-
A UPS is a battery-powered device designed to provide backup power to electronic equipment in the event of a mains power failure.
Some models can also be used to stabilize the electrical power being delivered to your equipment, by boosting or trimming the mains voltage.
Options
-
UPSs are available with a range of different power capacities. The one you select will depend on the equipment you plan to connect to it and how long you need the UPS to work in the event of a power failure.
You can select various styles of UPS, for example freestanding units that can be placed under desks or rack-mountable models to locate in server racks.

Features
-
Cheaper UPS models may simply act to provide battery power that activates when mains power fails.
More advanced models are likely to have advanced sets of features. These include software suites that instruct PCs or servers to shut down following power loss to prevent damage to data files, and logging software to monitor input voltages and power surges.
