PROBLEM TO BE SOLVED: To provide a power supply system which will not simultaneously supply the AC power to the power supplies disposed in a plurality of electronic devices, but can supply the AC power thereto with the differences. SOLUTION: In this power supply system 100, a solid-state relay(SSR) 31 supplies the AC power source received at a power source input terminal E1 to a corresponding power supply 21 from a power source output terminal T1, when the AC power source is supplied to the SSR 31 to 3n from a main switch 40. For example, an SSR 32 among the successive SSRs t32 to 3n receives AC power source outputted from the power supply output terminal T1 with a control signal input circuit C2 and supplies the AC power source of the power source input terminal E2 to the corresponding power supply 22 from the power source output terminal T2, under these conditions. The SSRs 33 to 3n sequentially supply the AC power source to the corresponding power supplies for each constant period (one cycle of the AC power source). |
