Abstract: An integrated power hub and device controller apparatus, and associated operational method, are operable to control and supply power to electrical devices that operate in environments which create a high risk for the electrical devices to generate stray voltages and currents. According to one embodiment, the apparatus includes a plurality of converter circuits, a controller, and a communication interface. The converter circuits convert input AC power to DC power such that each converter circuit provides a DC output voltage for a respective electrical device. The converter circuits may be configured (e.g., with toroidal step-down transformers) so as to mitigate stray currents from flowing between the electrical devices. The controller is operable to generate control signals so as to at least partially control operations of the electrical devices. The communication interface is operably coupled to the controller and operable to provide the control signals to the electrical devices.
