Abstract

An AC/DC electrical distribution panel includes a housing, a line voltage alternating current (AC) port configured for connection to an electrical distribution grid at line voltage, and a low voltage direct current (DC) port configured for connection to a DC load. A circuit board assembly is electrically coupled to the AC port and the DC port, and includes an AC connector array coupled to the AC port, and a DC connector array coupled to the DC port. One or more modular AC/DC power supplies are removably coupled to the AC and DC connector arrays. A processor is operatively engaged with the circuit board assembly, and configured to selectively switch the power supplies on and off. The circuit board assembly includes a current meter configured to monitor the current load being drawn from the DC port, wherein the processor is configured to selectively activate and deactivate various power supplies in response to the monitored current load.
