Abstract
A control unit is configured to perform stop control of causing a power supply circuit to stop supplying a supply current, if the supply current is determined to exceed a threshold, determine whether an input alternating current (AC) voltage is abnormal, with supply of the supply current to the power supply circuit stopped by the stop control, and cause the power supply circuit to resume supplying the supply current, if the input AC voltage is determined not to be abnormal.
