Abstract
A variable-range power supply for a model vehicle layout, such as a model train track for powering model trains or the like, is configured to receive a control input defining respective ends of an output voltage range. The control input may correspond to opposing ends of a range of motion for a hand-operated actuator, or other control input. The power supply further includes a controller configured to allow a user to select a desired output voltage level for a minimum or maximum of the output range. Output power is maintained within the user-specified range.
