Low voltage dc electrical outlets

A low voltage DC power outlet assembly comprising:

• a circuit subassembly comprising a power supply and a controller;
• electrical input conductors and electrical output conductors, wherein the electrical input conductors are coupled to the power supply and are configured to receive and convey line voltage from a power source to the power supply, and wherein the power supply is configured to transform the line voltage input via the electrical input conductors to a low voltage DC output of about 20V DC;
• a low voltage power outlet comprising at least two electrical receptacles having different physical dimensions, wherein the at least two electrical receptacles comprise at least one USB Type-A outlet and at least one USB Type-C outlet;
• and
• a housing configured to be mounted in a user-accessible location, wherein the housing is configured to slidably engage an elongate channel member of a power and/or data assembly, and wherein the circuit subassembly and the low voltage power outlet are arranged in the housing;
• wherein the housing is a unitarily formed box-shaped enclosure, and comprises a faceplate formed of resinous plastic, which faceplate is configured for providing access to the at least two electrical receptacles of the low voltage power outlet, wherein the faceplate comprises a plurality of spaced-apart openings, each opening having different dimensions for providing access to a respective one of the at least two receptacles;
• and
• wherein the electrical output conductors are coupled to the controller of the circuit subassembly and to the low voltage power outlet, and convey the low voltage output from the power supply, via the controller, to both of the at least two electrical receptacles of the low voltage power outlet, and wherein the controller is configured to downconvert the low voltage output of about 20V DC to supply about 5V DC at about 2 amperes to both of the at least two electrical receptacles of the low voltage power outlet.
