How Does an Uninterruptible Power Supply Work?
A UPS system acts as a backup power supply as well as a surge protector. It connects to the main power source (wall outlet) and directly to the application or to a power distribution unit connected to multiple devices. If the power fails, the UPS automatically switches to its battery pack to start powering the devices. This solution provides a company with sufficient time to assess power problems, troubleshoot equipment and /or store electronic documents and data. The amount of backup power provided by the UPS system depends on the capacity of the battery pack and the power demand of the connected equipment.
In some configurations, two UPS systems may be connected. If the first UPS system runs out of battery power or experiences a failure, the second UPS system kicks in to provide backup power.
