Abstract
A constant voltage power supply that includes an enclosure and a transformer positioned within the enclosure. The transformer has a primary winding and first and second sets of secondary windings mounted and magnetically coupled to each other all on a single magnetic core structure. The primary winding is connected by primary circuitry to a source of electrical power. First secondary circuitry is connected to the first secondary winding set for supplying electrical power at regulated constant voltage. Second secondary circuitry is connected to the second secondary winding set for supplying auxiliary power at unregulated voltage.
