Abstract: The invention relates to a system for supplying direct electric power to at least two loads from an alternating electric power source comprises a circulation bus for the alternating power adapted to be connected to the alternating power source and at least one converter for converting alternating power into direct power, connected to the circulation bus. The system further comprises at least two connection interfaces, each connection interface being connected to a corresponding converter and being adapted to be connected to at least one electric load to supply direct electric power for the or each corresponding load; and means for controlling the connection interfaces, the control means being capable of time-shifting the start-up moment for the supply of direct power from one interface to the other.

Abstract: An electrical panel having an unpluggable drawer unit that forms a housing for positioning an electrical device, and an Ethernet-type high-frequency communication device that forms a daisy-chain communication subsystem, the one drawer unit including an unpluggable connector to connect or disconnect it to a communication subsystem, and the drawer unit can occupy a first, plugged-in position connected to the communication subsystem, and it comprises a switch that controls a bypass switch of a bypass on the communication subsystem when the drawer unit occupies a second, unplugged position.
