<p>PROBLEM TO BE SOLVED: To solve the problem of the external wiring of power source equipment and an uninterruptible power supply being necessary, when a power supply system is constructed, so that man-hours are necessary for its wiring. SOLUTION: A first, a second and a third power supply units 1, 2, 3, which are connected in parallel, are combined with an uninterruptible power supply unit 4 using DC output side connectors 17B-1, 17B-2 and DC input side connectors 17A-1, 17A-2. Thereby a DC bus line 40 of the uninterruptible power supply unit 4 is connected with DC bus lines (Vo+), (Vo-) of the first, second and third power supply units 1, 2, 3, at single-action operation.</p> |
