Control method and unit of an electric system for supplying power/electric current to sockets for the passengers of an aircraft

Control unit (10) of an electric system (7) for supplying power/electric current to sockets (9) for the passengers of an aircraft (1);

• the control unit comprises:
• a memory device (14) for storing a maximum power/electric current deliverable to the sockets (9);
• a sensor device (15) for cyclically detecting the power/electric current absorbed by the sockets (9);
• a remote-controlled switch (12) for each socket (9) or for each group of sockets (9);
• and
• a processing device (11) which, if the power/electric current absorbed by the sockets (9) is higher than the maximum power/electric current, disconnects one or more sockets (9) from the electric supply by using the relative switches (12) until the power/electric current absorbed by the sockets (9) is lower than the maximum power/electric current;
• if the power/electric current absorbed by the sockets (9) is remarkably lower than the maximum power/electric current, connects again one or more sockets (9) to the electric supply by using the relative switches (12) until the power/electric current absorbed by the sockets (9) is close to the maximum power/electric current;
• and periodically varies the sockets (9) connected/disconnected to/from the electric supply by using the relative switches (12) so that each socket (9) is connected to the electric supply for a first period of time (Ton) and is disconnected from the electric supply for a second period of time (Toff).
