Summary:PROBLEM TO BE SOLVED: To provide a DC power source device which realizes not only a high output and a high reliability but also a low cost. SOLUTION: This device is provided with power source device parts 3 (31 to 33) and a common control part 2, and each power source device part 3 is provided with a power source device part main body 38 which outputs a DC voltage, an output voltage varying means 33 of this device part main body, and an individual control part 30 having a communication means 31 with the outside, and the common control part 2 is provided with an output voltage detection means 23, which detects the output voltage of the power source device part 3, and a communication means 21 with the outside. The common control part 2 obtains the difference between output voltage information from the output voltage detection means 23 and a preliminarily set target voltage and second indication information corresponding to this difference to individual control parts 30, and individual control parts 30 change the output voltages of power source device main bodies 38 by a preliminarily set value in accordance with received indication information, thus stabilizing the output voltages of power source device parts 3 (31 to 33).
