FIELD: electrical engineering.
SUBSTANCE: invention relates to the field of electrical engineering, in particular to system (1) of DC power distribution. System comprises power source (5) supplying DC power to rail (2) to which the electrical load (9, 10) is connected. Communication device (11) is connected to rail (2), which a) wirelessly receives communication signals and transmits the received communication signals via the power line communication provided by the rail to power source (5) and/or electric load (9, 10), and/or b) receives communication signals via power line communication from power source (5) and/or electric load (9, 10), and transmits the received communication signals wirelessly.
EFFECT: providing a communication setup that provides easy integration of management functionality for management, for example, a power source and/or an electrical load by transmitting control signals through a communication device.
