PROBLEM TO BE SOLVED: To achieve power saving of a power source system.SOLUTION: A power source system S includes: a switching power source 20 which converts an AC voltage from an AC power source 15 into a predetermined DC voltage and outputs the predetermined DC voltage; a control device 80; and a capacitor C1 which is connected to the AC power source 15 in parallel with the switching power source 20 and stores power by a charging current supplied from the AC power source 15. The power source system S further includes: an auxiliary power source circuit 50 which supplies power to the control device 80; and a relay 60 which switches a connection state of the auxiliary power source circuit 50 with respect to the AC voltage power source 15. When causing the switching power source 20 to start, the control device 80 switches the relay 60 to a state where the auxiliary power source circuit 50 is separated from the AC power source 15. |
