  • the control unit 30 of the relay unit 2 starts the control operation required during the power failure based on the power failure notification signal received by the communications unit 33.
  • the control unit 30 stores in the storage unit 34 the power feeding states of the load circuits at that time (immediately before the occurrence of the power failure) and, then, turns on only the circuit opening/closing control units 32a to 32d set by the setting switches 35c and turns off the other circuit opening/closing control units 32a to 32d.
  • the DC power can be supplied to only load circuits connected to desired DC devices 4 including, e.g., an LED lighting device, so as to operate only the desired DC devices 4.

Abstract

L'invention concerne un système de commande de charge qui comprend: une unité de commande d'alimentation électrique permettant de réguler l'alimentation en courant continu de multiples dispositifs de charge via des premières lignes électriques; et une pluralité de bornes de commande de charge connectées à l'unité de commande d'alimentation électrique via une seconde ligne électrique, et actionnées par une alimentation en courant continu fournie par la seconde ligne électrique. Les signaux de commande de charge reçus par l'unité de commande d'alimentation électrique des bornes de commande de charge, par le biais de courants porteurs en ligne, lui permettent de commander l'alimentation en courant continu des dispositifs de charge.
