1. A configurable light emitting diode (LED) driver/dimmer for controlling a set of light fixture loads comprising:
- a power circuit including;
an inrush current limit;
a DC/DC converter;
a power factor correction (PFC) boost connected to the inrush current limit and the DC/DC converter;
a regulated output voltage bus connected to the DC/DC converter; and
a primary controller for controlling the power circuit;
a set of output current drivers, each of the set of output current drivers connected to one of the set of light fixture loads for controlling the associated light fixture load; and
at least one power limit associated with the set of output current drivers;
a secondary controller for controlling the set of output current drivers;
wherein the secondary controller transmits LED control information to control outputs of the set of output current drivers; and
wherein the secondary controller receives a program comprising an algorithm for converting an input signal to the LED control information and establishes a conversion between the input signal and the LED control information based on the algorithm.

Abstract
The disclosure is directed at a method and apparatus for configuring and powering light fixture loads for a LED low voltage distribution system. The method and apparatus include converting power being supplied for powering the set of light fixture loads and then limiting this converted power to a set of multiple current outputs supplied to the light fixture loads. The multiple current outputs are then split or regrouped prior to being delivered to the light fixture loads.
