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.
