Abstract

La présente invention porte sur un dispositif d'alimentation électrique pour caméra de télévision en circuit fermé. Le dispositif de la présente invention comprend : un boîtier ; une unité d'alimentation à découpage (SMPS), qui présente une structure constituée de multiples canaux d'alimentation, qui est montée sur le boîtier, et qui convertit une puissance en courant alternatif (CA) commercial d'entrée en puissance d'attaque en courant continu (CC) et fournit la puissance d'attaque CC convertie à une pluralité de caméras de télévision en circuit fermé ; et une unité de commande pour commander le fonctionnement de l'unité SMPS. L'unité SMPS comprend des cartes SMPS séparées. Il existe plus de cartes SMPS qu'il n'existe de canaux d'alimentation, et l'unité de commande fonctionne de façon à permettre à une carte SMPS préliminaire de maintenir l'alimentation électrique lorsque l'une des cartes SMPS séparées tombe en panne. Selon la présente invention, par utilisation de multiples canaux d'alimentation pour une pluralité de caméras avec un seul dispositif d'alimentation électrique, même lorsqu'un canal tombe en panne, l'état d'alimentation électrique peut être maintenu au moyen de la commutation automatique d'un canal à un canal préliminaire. Etant donné que des cartes SMPS séparées constituant de multiples canaux d'alimentation sont détachables par coulissement, la maintenance peut être améliorée.
