PROBLEM TO BE SOLVED: To supply an AC current for efficiently driving an instrument for a maintenance line by converting a first AC current that is introduced from an introduction part to a second AC current with a second frequency that is higher than a first frequency and a second voltage that is higher than a first voltage, and supplying the second AC current to the instrument for the maintenance line. SOLUTION: A power-supplying device 10 is provided with a housing, An introduction part 20 is provided on a side surface 11 a of the housing, and a current supply part 30 is provided on a side surface 11 b. A conversion part 40 is provided in the housing. The introduction part 20 is connected to the input terminal of an inverter via wiring, and the current supply 30 is connected to the output terminal of the inverter via wiring. A frequency selection switch 44 is connected to a frequency selection terminal, and the inverter has a function for converting an inputted AC current, thus efficiently performing driving and improving working efficiency. |
