Abstract: A selectable source input power supply is disclosed. According to one embodiment, a power supply is provided comprising an input stage including an input connector to couple the power supply to either of an AC input voltage or a DC input voltage, and an actuatable input switch to determine which of the AC input voltage and the DC input voltage is coupled to the power supply, to couple the input stage to an alternating current path in response to a determination that the AC input voltage is coupled to the power supply, and to couple the input stage to a direct current path in response to a determination that the DC input voltage is coupled to the power supply.
