Abstract
In one embodiment, a power system for a plurality of dispensers comprises an AC transformer to receive a line voltage and generate an output voltage of about 2 volts AC to about 50 volts AC; a plurality of dispensers, each housing at least one electrical component operatively configured to dispense product through a dispensing aperture, each of the dispensers comprising a battery compartment; and a plurality of power converters adapted to be at least partially disposed within the battery compartments such that at least one power converter is associated with each dispenser, the converters disposed in communication with the AC transformer such that the power converters receive the output voltage and provide a DC voltage to one or more electrical components housed within the dispensers.
