ABSTRACT:
An uninterruptible power supply apparatus is equipped with a power supply input section a2and a power supply input section b3that receive two systems of power supply, respectively; a power supply output section a4and a power supply output section b5that output the power supply inputted in the power supply input section a2and the power supply input section b3, respectively; and a control section7that detects a power failure state of the power supply that is inputted in at least of the power supply input section a2and the power supply input section b3, and outputs a backup power supply from at least one of the power supply output section a4and the power supply output section b5based on a detection result obtained by the control section7.
