Abstract
A voltage adapter for use with DC operable devices and for deriving a DC output voltage from either an AC voltage power source or a DC voltage power source. The voltage adapter, which is selectively coupled by a cable assembly to either a DC voltage power source or an AC voltage power source, includes separate voltage regulators for regulating a DC output voltage derived from the AC voltage and a DC output voltage derived from the DC voltage. The voltage adapter also allows selection of the amplitude for the DC output voltage within a range.
