Abstract
(EN) A power circuit for a recreational vehicle includes a plurality of electronic devices of the recreational vehicle that require direct current (DC) power for operation. Each of the plurality of electronic devices includes a circuit board. The power circuit for a recreational vehicle also includes a single DC power supply electrically coupled directly to a first circuit board of a first electronic device of the plurality of electronic devices via a first wired connection. Thus, the DC power is supplied to the first electronic device. Further, the power circuit also includes electrically coupling the remaining circuit boards of the plurality of electronic devices to the first circuit board via a daisy chain sequence separate from the first wired connection. Accordingly, the remaining circuit boards of the plurality of electronic devices receive the DC power from the single DC power supply via the daisy chain sequence.
(FR) Un circuit d'alimentation pour un véhicule de loisirs comprend une pluralité de dispositifs électroniques du véhicule de loisirs qui nécessitent une alimentation en courant continu (CC) pour le fonctionnement. Chacun de la pluralité de dispositifs électroniques comprend une carte de circuit imprimé. Le circuit d'alimentation pour un véhicule de loisirs comprend également un seul bloc d'alimentation en CC couplé électriquement directement à une première carte de circuit d'un premier dispositif électronique de la pluralité de dispositifs électroniques par l'intermédiaire d'une première connexion filaire. Ainsi, l'alimentation en courant continu est fournie au premier dispositif électronique. En outre, le circuit d'alimentation comprend également le couplage électrique des cartes de circuit imprimé restantes de la pluralité de dispositifs électroniques à la première carte de circuit imprimé par l'intermédiaire d'une séquence de connexion en cascade distincte de la première connexion filaire. En conséquence, les cartes de circuit imprimé restantes de la pluralité de dispositifs électroniques reçoivent l'alimentation en courant continu en provenance du bloc d'alimentation en courant continu unique par l'intermédiaire de la séquence de connexion en cascade.
