The DC circuit is converted to a DC voltage output. [0005] The AC-to-DC circuit of the conventional dual-input power supply has a transformer and a fuse as an overcurrent isolation and protection; however, the DC-to-DC circuit has no protection design. Therefore, if the DC input terminal of the dual input power supply has excessive current, it will easily cause damage to the appliance. Moreover, the conventional dual-input power supply displays and controls the output voltage on a scale; it is very easy to misjudge and mistouch to change the output voltage.
