Zusammenfassung:	To provide a power supply unit capable of performing maintenance in a state where the power supply to some of the multiple equipment units is continued.SOLUTION: A power supply unit 120 is a power supply unit that supplies the electric power to multiple equipment units including: a first circuit board 11; a power reception part 20 provided to the first circuit board 11; multiple voltage conversion units 41, 42 that convert the voltage of the electric power supplied to the power reception part 20 and output the same; and a power supply switching unit that is placed on a wiring route connecting the power reception part 20 and the multiple voltage conversion units 41, 42 for switching the power supply on/off to the multiple voltage conversion units 41 and 42 individually.SELECTED DRAWING: Figure 4 【課題】複数の機器ユニットのうち一部の機器ユニットへの電力供給を継続した状態で電力供給ユニットの保守を行う。【解決手段】電力供給ユニット１２０は、複数の機器ユニットに電力を供給する電力供給ユニットであって、１つの第１の回路基板１１と、第１の回路基板１１に設けられた受電部２０と、受電部２０に供給された電力の電圧を変換して出力する複数の電圧変換部４１、４２と、受電部２０と複数の電圧変換部４１、４２とを繋ぐ配線経路上に配置され、複数の電圧変換部４１、４２への給電の有無を個別に切り替える電力供給切替部とを備える。【選択図】図４
