Short for uninterruptible power supply, a power supply that includes a battery to maintain power in the event of a power outage. Typically, a UPS keeps a computer running for several minutes after a power outage, enabling you to save data that is in RAM and shut down the computer gracefully.
In a multiple output power supply it is sometimes awkward to have every output voltage spot-on. Power supply centering refers to this. This is often due to things like needing a full integer wind on a transformer. So, although the voltage might be well regulated, the nominal voltage can be slightly off.
