A ferroresonant transformer assembly comprising, a core, a main shunt, first, second, and third windings, first and second tap connectors, and a selection connector. The first windings configured to be operatively connected to a primary power source. The first tap connector operatively connected to a first intermediate point defined by the third windings. The second tap connector operatively connected to a second intermediate point defined by the third windings. The selection connector operatively connected to the at least one load. Based on voltage requirements of the at least one load, the selection connector is operatively selectively connected to a selected tap connector selected from the first and second tap connectors.
