Abstract

L'invention concerne un dispositif de commande (100) de gradateur qui détermine quand doit être commuté un niveau de tension amenée à un luminaire (160) constitué d'une pluralité d'ampoules (162), par surveillance de la relation de phase entre une tension d'entrée (190) et un courant d'entrée (180). Lorsque cette relation de phase est située dans des limites de tolérance acceptables, des entrées de commande extérieures pour abaisser, c'est-à-dire atténuer, ou augmenter le niveau d'illumination sont acceptées et traitées. Ce dispositif de commande (100) de gradateur compense d'autre part des transitions de réchauffement ou d'amorçage en dirigeant la tension d'entrée (190) à travers des relais (290) qui fournissent une tension maximale jusqu'à ce que la relation de phase tension/courant voulue soit établie dans des niveaux de tolérance acceptables. Ce dispositif de commande (100) de gradateur fournit également une tension de sortie maximale lorsqu'une défaillance ou des conditions anormales sont déterminées.
