To provide a power source system that generates no leak current through a communication line for communication in the power source system that requires no change in hardware even when a system configuration is changed and the number of output power sources and their voltages are changed, and the power source system that communicates with at least one of a plurality of load apparatuses to which the power supply system itself supplies electric power.SOLUTION: Power is adapted to be supplied to a UART communication circuit 623 in a load apparatus 604 only when power supply to an external output terminal 644 for supplying power to the load apparatus 604 for communicating with a power supply system 600 is ON.SELECTED DRAWING: Figure 6 【課題】 システム構成が変更になり、出力電源数やこれらの電圧が変化した場合においても、ハードウェアの変更を行う必要のない電源システム、および、自らが電力供給する複数の負荷機器のうち、少なくとも一つと通信を行う電源システムにおいても、上記通信のための通信線を通して漏洩電流が発生しない電源システムを提供する。【解決手段】電源システム６００と通信を行う負荷機器６０４へ電力供給するための外部出力端子６４４への電力供給がＯＮのときのみ、負荷機器６０４内のＵＡＲＴ通信回路６２３に電力を供給するようにする。【選択図】図６
