Le convertisseur de bus 1 kW \u00e0 fr\u00e9quence fixe et enti\u00e8rement r\u00e9gul\u00e9 offre un rendement sans pareil dans l’industrie de 97%. D\u00e9velopp\u00e9s par Murata Power Solutions \u00e0 la norme DOSA 1\/4 de brique, les modules DRQ-11.4\/88-L48xx sont propos\u00e9s avec de nombreuses fonctions et options standard, dont  la r\u00e9partition de charge de deux modules ou plus en parall\u00e8le, la protection pr\u00e9-polarisation, des options de logique de commande de marche\/arr\u00eat positive et n\u00e9gative, ou encore la protection contre les courts circuits, les surintensit\u00e9s\/surtensions et les surchauffes. La s\u00e9rie DRQ-11.4\/88-L48 supporte la pr\u00e9-polarisation au d\u00e9marrage, ce qui permet de supprimer les courants inverses au d\u00e9marrage et \u00e0 l’arr\u00eat.<\/p>\n

Homologu\u00e9s pour la s\u00e9curit\u00e9 pour les applications r\u00e9seau et t\u00e9l\u00e9com, les modules offrent une isolation op\u00e9rationnelle des E\/S de 1500 Vdc. Pour garantir une fiabilit\u00e9 optimale, la s\u00e9rie DRQ-11.4\/88-L48 est con\u00e7ue et test\u00e9e aux conditions de l’IPC-9592, R\u00e9vision B. La plaque de base int\u00e9gr\u00e9e am\u00e9liore les performances thermiques, et le rendement de 97% permet un bon refroidissement pour la fiabilit\u00e9 et la long\u00e9vit\u00e9.<\/p>\n

Les principales applications pour le DRQ-11.4\/88-L48 de Murata sont les \u00e9quipements d’infrastructure r\u00e9seau et t\u00e9l\u00e9com, les \u00e9quipements de communications, la s\u00e9curit\u00e9 r\u00e9seau, les routeurs, les stations de base sans fil, les commutateurs et l’\u00e9lectronique t\u00e9l\u00e9com, les \u00e9quipements informatiques et autres applications n\u00e9cessitant une conversion de puissance \u00e0 une tension de bus interm\u00e9diaire de 11,4 V.<\/p>\n
