Title
(EN) POWER OVER ETHERNET DELIVERY METHOD AND SYSTEM
(FR) PROCÉDÉ ET SYSTÈME DE DISTRIBUTION D'ALIMENTATION ÉLECTRIQUE PAR CÂBLE ETHERNET
Abstract
(EN) A Power over Ethernet (PoE) system and method that can provide greater power efficiency and reduces greenhouse gas emissions is described. The PoE system includes power supply equipment, Ethernet cabling, and a powered device. When a load is not present at the end of the Ethernet cabling, an injector in the power supply equipment enters a sleep state, thus conserving power and increasing efficiency. When the injector is electrically connected to a load, such as the powered device, a circuit in the injector activates power to a digital control logic and subsequently provides power to a sensing conductor in the Ethernet cable, thereby enabling high efficiency power transfer.
(FR) L'invention concerne un système et un procédé d'alimentation électrique par câble Ethernet (PoE) qui peut fournir une plus grande efficacité d'alimentation et réduit les émissions de gaz à effet de serre. Le système PoE comprend un équipement d'alimentation électrique, un câblage Ethernet, et un dispositif alimenté. Lorsqu'une charge n'est pas présente à la fin du câblage, un injecteur dans l'équipement d'alimentation passe à un état de veille, permettant ainsi de conserver de l'énergie et d'augmenter l'efficacité. Lorsque l'injecteur est électriquement connecté à une charge, tel que le dispositif alimenté, un circuit dans l'injecteur active l'alimentation vers une logique de commande numérique et alimente ensuite un conducteur de détection dans le câble Ethernet, ce qui permet un transfert d'alimentation à haute efficacité.
