Abstract: The present invention relates to a power management and distribution device (4) for powering a personal electronic device via a direct current outlet unit (6a; 6b; 6i) at a passenger seat in an airplane cabin, the power management and distribution device (4) comprising: a first interface (12) for receiving electrical supply power (10); a second interface (14) for supplying electrical supply power (10) received at said first interface (12) to another power management and distribution device (4i); a third interface (16) for supplying electrical supply power (10) received at said first interface (12) to the direct current outlet unit (6a; 6b; 6i) for the personal electronic device; a further interface (15; 17) for supplying electrical supply power (10) received at said first interface (12) to either an inflight entertainment screen (17a; 17b; 17i) or an alternating current outlet (5a; 5b; 5i) at the passenger seat; a power measurement device (82, 80; 85) configured to measure the electrical outlet power (20) dra

Abstract: The present invention relates to a power management and distribution device (4) for powering personal electronic devices via outlet units (6a, 6b) at passenger seats in an airplane cabin, wherein the power management and distribution device (4) comprises a first interface (12) for receiving electrical supply power (10) from a master control unit (2) connected to a primary power source (3), a second interface (14) for supplying electrical supply power (10) received at said first interface (12) to another power management and distribution device (4i), a third interface (16) for supplying electrical supply power (10) received at said first interface (12) to the personal electronic devices via the outlet units (6a, 6b), and a control unit (18) configured to control the electrical outlet power (20) drawn by the personal electronic devices via the outlet units (6a, 6b).

Abstract: An electrical outlet has socket openings for insertion of contact pins of an electrical plug therein, a closure element that selectively closes or opens the socket openings, and a latching element that selectively latches or unlatches the closure element. The closure element slides perpendicularly to the insertion axis. The latching element includes a latching pawl that is flexibly deflectable parallel to the insertion axis, between a latched position for engaging the closure element and an unlatched position for releasing the closure element. An unlatching pin of an adapter is inserted to deflect the latching pawl to disengage it from the closure element. This unlocks the receptacle for use. Then the contact pins of the plug may be inserted through holes in the adapter and into the socket openings to press sloping surfaces of the closure element to slide the closure element to the open position.
