FONCTIONNEMENT SUR LE SECTEUR ET TEMPÉRATURES RÉSULTANTES

Les tableaux suivants vous apporteront une aide précieuse dans la détermination du choix de l’alimentation et des câbles.

Le courant secteur est converti en signal de sortie afin d’alimenter les haut-parleurs connectés mais aussi en chaleur. La différence entre le courant utilisé et la puissance restituée est appelée perte de puissance ou dissipation (Pd). La quantité de chaleur résultant de la dissipation de puissance a tendance

àrester prisonnière du rack et doit être expulsée par des moyens appropriés. Le tableau suivant a pour objet de vous aider à calculer les températures à l’intérieur d’une armoire de rack et les moyens de ventilation nécessaires.

La colonne “Pd” indique la dissipation en fonction des différent modes de fonctionnement. La colonne “BTU/hr” indique la quantité de chaleur dispensée par heure.
