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.
Short for Standby Power Supply, an SPS contains a circuit that is capable of telling if and when a disturbance in electricity occurs. When a disturbance occurs, the SPS switches to battery power, however, if the SPS switch time is not fast enough, all power may still be lost.Higher quality SPS systems offer a ferroresonant transformer that offers a small amount of power while switching takes place.hen a disturbance occurs, the SPS switches to battery power, however, if the SPS switch time is not fast enough, all power may still be lost.
