PROBLEM TO BE SOLVED: To solve the problem of wiring being complicated, because a power supply is connected with a load function device by using external wiring, influence due to noise is apt to be applied, malfunctions are apt to be generated, and practical use is hindered. SOLUTION: AC input bus lines (Vin+), (Vin-), DC output bus lines (Vo+), (Vo-) and a current balance signal bus line (CB) which are used for connecting a first, second and third power source units 1, 2, 3 are subjected to connector connection, and a module power source is constituted; and an additional function unit 4 is connected with the module power source by using a connector, and added, thereby realizing a power source device having additional function which saves wiring and has large resistance of noise. |
