Abstract
A power supply system includes a switching power supply for outputting a predetermined DC voltage by converting an AC voltage from an AC power supply, a latching relay provided on an AC input line for switching a connection state of the switching power supply and the AC power supply in response to a relay drive signal, a storage circuit storing electricity from the switching power supply, a control device for receiving electric power from the storage circuit in a disconnection state, and a relay drive circuit for generating the relay drive signal and outputting it to the latching relay. The control device determines whether an amount of charge of the storage circuit has decreased to a predetermined amount of charge in the disconnection state, and generates and outputs the relay control signal to the relay drive circuit.
