How does a UPS work?
A UPS is used in many ways. For the sake of this explanation we will use a computer as an example of a typical UPS application. A UPS works by regulating power to the electronic items you have connected to it (in the event of power surges or brownouts)
- in the event of a power failure a UPS will alert you to the fact there is no power and depending on the size of the UPS can either shut down your computer or
- let your computer keep on running or
- alert you to the fact there is a power failure which will allow you to shut down your equipment yourself.
