Abstract: An electronic device, in particular a variable speed drive or alternator regulator, comprising a heat sink (10) and a power card comprising a printed circuit board, housed in a casing, characterized in that it comprises a part (100) attached, on the one hand, to the heat sink (10) and attached, on the other hand, to the board and coming into contact with at least one conductive track of the power card, so as to provide an electrical contact between the heat sink and said track, said part (100) having a face that is accessible from the outside of the device for attaching a lug connected to a ground and/or an earth cable.

Abstract: An assembly comprising: an electronic device (1), in particular a variable speed drive or alternator regulator, comprising a casing, the rear of which is equipped with a heat sink (10), produced from a metal profile section, for cooling at least one power component; a first assembly of elements (20) for attaching the device on a support, each comprising at least one tab to be engaged in the profile section by sliding it therein, and an attachment lug provided with at least one screw through-hole; a second assembly of elements for attaching the device on a support, each comprising at least one tab to be engaged in the profile section by sliding it therein, and an attachment lug provided with at least one screw through-hole, the elements being of different shapes.

Abstract: An electronic device (1), in particular a variable speed drive or alternator regulator, comprising at least one power component mounted on a heat sink (10) and a plurality of capacitors extending through at least one opening of the heat sink, characterized in that it comprises a recess, which accommodates a sheet seal that is applied, on the one hand, on an internal face of the heat sink and, on the other hand, on an internal face facing a casing fitted onto the heat sink, with the internal faces of the heat sink and of the casing coming into contact.

Abstract: An electronic device (1), in particular a variable speed drive or alternator regulator, comprising a casing, the front of which has a housing for accommodating an ancillary module, a hatch (150) for closing said housing, and an electronic circuit comprising an interface card defining a housing for accommodating a memory card, opening into the housing for accommodating the ancillary module
