Abstract

L'invention concerne un dispositif d'alimentation électrique pour panneau tactile, comprenant un adaptateur secteur, une batterie et un circuit de commutation de régulation; l'entrée de l'adaptateur secteur étant raccordée au secteur; la sortie de batterie et l'adaptateur secteur étant raccordés à l'entrée électrique du panneau tactile à l'aide du circuit de commutation de régulation de manière à assurer l'alimentation en électricité en alternance du panneau tactile à l'aide du circuit de commutation de régulation. L'utilisation de la structure décrite permet l'alimentation en électricité du panneau tactile à l'aide de l'adaptateur secteur en présence de courant d'alimentation, et l'alimentation en électricité du panneau tactile à l'aide du circuit de commutation de régulation pour utiliser la batterie en cas d'interruption de courant, ce qui permet de traiter le dérangement dû au panneau tactile qui est incapable de fonctionner en cas d'interruption de courant; l'invention permet également de résoudre l'inconvénient de l'état de la technique, à savoir le fait de devoir désassembler fréquemment un panneau tactile fonctionnant avec une batterie à piles sèches pour pouvoir remplacer la batterie à piles sèches.
