There is provided a power supply device having an overvoltage protection function against an overvoltage caused by a lightning strike, a power surge, or the like. The power supply device having an overvoltage protection function includes: a power supply unit inverting input power to supply driving power; a controller controlling an inverting operation of the power supply unit in response to an external control signal; and a protection unit interrupting the control signal provided to the controller to stop the inverting operation of the power supply unit when a voltage level of the input power is equal to a pre-set voltage level or higher. |
