Abstract
The invention relates to a DC-power supply device () for supplying operational DC-power to one or more DC-powered devices that have respective DC-power requirements, that comprises a power interface () for providing, via a single twisted-pair wired bus (), DC output power, a DC-power-supply network communication unit () configured to receive DC-power requirement information indicative of a DC-voltage requirement and a DC-current requirement for operation of the respective connected DC-powered devices, and a DC-power-supply control unit () configured to drive, in an initialization supply mode, delivery of initialization DC-output power amount, that is suitable for transmission by the DC-powered devices of respective DC-power requirement information, to determine, using the DC-power requirement information and a power-determination rule, and provide an operational DC output power for powering operation of at least one the DC-powered devices in its regular operation mode, thus enabling a powering of multiple DC-powered devices having different DC-power requirements.
