Abstract

The present application discloses systems and methods for providing low voltage power for low voltage lighting sources, e.g., so-called landscape lighting. A low voltage lighting power supply includes an enclosure and a power circuit enclosed in the enclosure. In some embodiments the power circuit has a primary side and a secondary side. The primary side accepts power from a main power source and the secondary side has a plurality of separate output power circuits, each output power circuit generating a separate low voltage lighting power signal capable of lighting a plurality of low voltage light sources and each being rated for a particular output.
