POWER SUPPLY BOX PROVIDED WITH HOT PLUG FUNCTION

摘要

PROBLEM TO BE SOLVED: To provide a power supply box furnished with a hot plug function which improves the stability of the actuated state of an operation system. SOLUTION: This power supply box is provided with two hot plug devices and a power supplying device. The first hot plug device is provided with the first output terminal 21 and the second output terminal 22, which transmit AC power from an AC power supply. Connected to the first output terminal 21, the power supplying device outputs DC by converting the AC outputted from the first output terminal 21 into DC. A second hot plug device comprising a first input terminal 31 and a second input terminal 32 is connected to the system above and the first power supplying device. The first input terminal 31 is connected to the first power supplying device, which transmits DC to this system. If an additional power supply is required for the system, another power supplying device is connected between the second input terminal 32 and the second output terminal 22 of the first hot plug device. The another DC is combined by the second hot plug device to be inputted into the power supply for the system.
