DC POWER DISTRIBUTION SYSTEM

摘要

The invention relates to a DC power distribution system (1) comprising a power supply (50) for supplying DC power to an electrical device (11) like a luminaire, wherein the system includes a connection device (4) comprising a connection device contact (5) to which an electrical device contact (19) of the electrical device is to be connected, a load presence detection unit (7) for detecting whether the electrical device contact has been connected, and a power providing control unit (6) for providing the DC power of the DC power distribution system to the connection device contact, only if the load presence detection unit has detected that the electrical device contact of the electrical device has been connected to the connection device contact. Thus, a voltage is not applied to the connection device contact, if the electrical device is not connected, thereby reducing corrosion effects and the likelihood of installers getting electrified.
