Abstract

Systems and methods described herein provide examples of an electrical panel (e.g., a modular electrical panel) that is configured to control a plurality of electrical loads. The electrical panel may include a control circuit, memory, a communication circuit, and an alternating current (AC) line feed and/or a direct current (DC) line feed. The electrical panel may also include a plurality of power supplies and a plurality of control modules, where more than one control module is associated with each of the plurality of power supplies. Each control module may configured to receive DC power from the associated power supply and provide an output voltage to at least one electrical load. The electrical panel provides flexibility as to whether each stage of conversion, regulation, and/or control is performed at a control module located within the electrical panel or performed at an accessory module located at an electrical load.
