PROBLEM TO BE SOLVED: To provide a power supply device capable of reduce power consumption in association with a multiplexed power supply.SOLUTION: The power supply device includes power supply control means which further includes: first switch-on/off means for connecting/disconnecting power fed from a feeding line; a first power unit which outputs power fed from the first switch-on/off means; second switch-on/off means for connecting/disconnecting power fed from the feeding line; a second power unit which outputs power fed from the second switch-on/off means; power supply connection means which outputs power, output from the first power unit and the second power unit, to a power supply line; first fault detection means for detecting the occurrence of a failure in the first power supply unit to output first fault detection information; and power supply control means which controls the second switch-on/off means to start power supply from the feeding line to the second power unit, on the basis of the first fault detection information.SELECTED DRAWING: Figure 1 |
