Boitier très sympa. Il y a tout ce qu'il faut pour faire une alimentation à partir d'un module DPS 5005
Par contre la partie puissance doit être à l’extérieur du boitier. Donc il faudrait un autre boitier contenant une alimentation 110 ou 220V, fournissant Une tension continue de 55V maximum ou moins.
Du coup le projet devient moins attrayant. J'ai donc décidé de rassembler la partie puissance dans ce mini boitier. J'ai réussi à intégrer un transfo 2x12V_1.25 Amp et 4 condensateurs de filtrage 4700µF mis en parallèle et un pont de diodes. Le tout sur un circuit imprimé fait main taillé dans un morceau de simple face de 90x55mm et découpé pour laisser la place au transfo torique. Le PCB offre 2 sorties de puissance pour L'entrée du module DPS 5005 et pour la platine du FAN.
Pour terminer, un problème de place c'est posé pour le fusible de protection sur la tension secteur, j'ai dû fixer le porte fusible sur le capot du boitier, je n'avais pas d'autre solution.
Je l'ai fixé avec vis , écrous et entretoise en nylon.
Une indication visible sur le boitier autorisant l'ouverture de celui ci à condition de débrancher la prise de courant 220V
