Abstract: A dynamic voltage switching system for a casing assembly of an outdoor lighting modular power supply, includes at least one relay operationally connected to a microcontroller unit (MCU) of the casing assembly of an outdoor lighting modular power supply, said at least one relay being configured to facilitate the switching of the output voltage of the modular power supply. Means are included for communicating voltage level commands from a switch mechanism to the relay to regulate the output voltage of the dynamic voltage switching system.

Abstract: A modular power supply system including an enclosure and a casing assembly contained within the enclosure. The casing assembly includes a plurality of slots. The casing assembly is configured to accept a plurality of transformer modules configured to slide into the slots. Each of the transformer modules is of a type having a transformer module housing, and a transformer element positioned within the transformer module housing.
