    Abstract: DC Power distribution system The invention relates to a DC power distribution system (1), especially a track lighting system, comprising several power supply units (3) and an electrical consumer (4) like a luminaire electrically connected to an electrical conductor (2)being preferentially a power bar. A power consumption information providing system provides power consumption information and a power supply control system controls the power supply units depending on the provided power consumption information. This allows adapting the DC power distribution to the actually required power, i.e. several power supply units can be electrically connected to the electrical conductor, without providing DC power in an inefficient operation condition. Moreover, the installation of the DC power distribution system can be relatively simple, because the installer just needs to attach a number of power supply units to the electrical conductor, which surely prevents an overload condition, wherein the DC power can still be supplied with high efficiency.
