The APC UPS is a battery backup system used to protect computer systems from power outages. It is typically used in small to medium-sized businesses and is a reliable way to keep systems up and running in the event of a power outage.
The APC UPS system consists of a battery pack, an APC back-up power unit, and an attached computer. The battery pack stores energy that is used to provide power to the APC back-up power unit.
If there is a power outage, the APC back-up power unit will start up and provide power to the attached computer.
