1. A system for controlling and distributing DC power comprising:
- a power hub comprisinga hub controller;
a power converter adapted to convert AC power to DC power;
one or more variable voltage regulators operatively connected to the power converter and controlled by the hub controller, the one or more variable voltage regulators are operable to provide regulated DC power to one or more primary loads and to receive and transmit data and control signals from and to the one or more primary loads;
one or more communication interfaces operatively connected to the hub controller to transmit and receive data and control signals over a network;
one or more primary loads, each primary load having a load control module, the load control module comprising;
a load controller operatively connected to the hub controller to receive and transmit data and control signals to the hub controller;
a plurality of output ports operatively connected to the load controller, the plurality of output ports adapted to provide DC power to secondary loads and to transmit and receive data and control signals to and from the load controller;
a load driver adapted to distribute DC power to the secondary loads, the load driver operatively connected to and under control of the load controller.

Abstract
A scalable DC power distribution and control system suitable for commercial buildings includes one or more power and control hubs. Each DC power and control power hub provides power and control for any suitable distributed DC loads such as light-fixtures. AC power from the electric utility is applied to the power and control hub and is converted to DC power for distribution to DC loads within the space using low-voltage cables.
