Abstract
(EN) The invention relates to a device (1) for monitoring and protecting an electric appliance (3), mounted on a power line (19) in series between a power source (2) and said appliance, comprising: at least one voltage regulator (10) for adjusting a supply voltage of the appliance (3); at least one current limiter (11) coupled to the voltage regulator (10) and adapted for reducing the supply voltage of the appliance (3) if a supply current absorbed by the appliance exceeds an upper operating value; at least one controlled short-circuit (13, 14) adapted to be triggered when the input voltage exceeds a safety limit value higher than the upper operating value and for cutting a fuse (115) mounted in series between the power source (2) and the appliance (3); and computation and storage means (20) for generating a clock signal and storing an anomaly occurrence date and operational parameters of the appliance power supply in a non-volatile memory.
(FR) L'invention concerne un dispositif (1) de surveillance et de protection d'un appareil (3) électrique, placé sur une ligne d'alimentation (19) en série entre une source d'énergie électrique (2) et ledit appareil, comportant : - au moins un régulateur de tension (10) adapté pour réguler une tension d'alimentation de l'appareil (3), au moins un limiteur de courant (11), couplé au régulateur de tension (10), adapté pour réduire la tension d'alimentation de l'appareil (3) si un courant d'alimentation absorbé par l'appareil excède une valeur supérieure de fonctionnement, au moins un court-circuit (13, 14) pilotable, adapté pour être déclenché lorsque la tension d'entrée excède une valeur limite de sécurité, supérieure à la valeur supérieure de fonctionnement et entrainer la coupure d'un fusible (15) placé en série entre la source d'énergie (2) et l'appareil (3), et - des moyens (20) de calcul et de mémorisation adaptés pour générer une horloge et enregistrer une date d'occurrence d'une anomalie et des paramètres de fonctionnement de l'alimentation de l'appareil dans une mémoire non volatile.
