An electrical controller includes a housing, wherein the housing has cooling air openings on two different housing sides. A heat sink is arranged inside the housing, in particular so as to be protected against contact, and forms a cooling air channel, wherein the cooling air channel runs between the cooling air openings of the different housing sides. An electrically insulating holding element is designed to mechanically fix the heat sink inside the housing in a manner electrically insulated from the housing. A number of components to be cooled are provided, wherein the components are thermally conductively coupled to the heat sink and are held by the heat sink.
