Abstract
A first excess current protector directs a controller to limit an output current of a regulator when a current value detected by a current detector exceeds a first preset current value set to be higher than a rated current value of a power supply device. A second excess current protector directs the controller to limit the output current of the regulator when an average value of the current value detected by the current detector over a predetermined period of time exceeds a second preset current value set to correspond to the rated current value. A third excess current protector directs the controller to limit the output current of the regulator when the current value detected by the current detector exceeds a third preset current value set to be lower than the second preset current value.
