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.
