The present invention addresses the problem of providing a stabilized power supply device capable of further improving reliability. A stabilized power supply device (10) is provided with a voltage adjusting unit (3) that outputs an inputted voltage from an output terminal unit (2) such that the voltage is within a predetermined voltage range, said inputted voltage having been inputted to an input terminal unit (1). The voltage adjusting unit (3) has a transformer (3a), a relay (3b), a control unit (3c), and a state detection unit (3d). The relay (3b) is configured to change electrical connection between the transformer (3a) and the input terminal unit (1) or the output terminal unit (2). The control unit (3c) monitors the inputted voltage, and controls switching of the relay (3b) such that an outputted voltage from the output terminal unit (2) is within a predetermined voltage range. The state detection unit (3d) detects the state of the relay (3b). |
