Abstract
A power source input device for both AC/DC power sources includes a first power source input unit that is provided at a power source input terminal of an electric power device to convert an AC or DC commercial power source selectively input from the outside into a DC driving power source and supply the converted DC driving power source to an accessory device. A second power source input unit is provided in the accessory device to supply the DC driving power source supplied from the first power source input unit to at least one load, thereby simplifying a configuration of a power source input terminal of each of the electric power devices and reducing a manufacturing cost thereof.
