Abstract

La présente invention se rapporte à un circuit de régulation d'alimentation électrique s'appliquant à des charges, telles que des systèmes d'éclairage à fluorescence. Un enroulement (3) comporte une extrémité positive (13) raccordée à un rail positif (1) et une prise de courant en un point prédéterminé (18) lui permettant de délivrer une tension sélectionnée à une borne de sortie (T). Un premier contact de relais (200A) peut raccorder électriquement une extrémité neutre (14) de l'enroulement à un rail neutre (2) pour établir une tension sélectionnée, ou un deuxième contact de relais (100A) peut court-cicuiter électriquement un nombre prédéterminé de spires de l'enroulement en réponse à une demande d'une seconde tension sélectionnée. Lorsqu'un état défaillant est détecté, un troisième contact de relais (300A) peut court-cicuiter électriquement l'extrémité neutre (14) de l'enroulement avec ledit point prédéterminé (18) afin de ramener le système en situation d'autoprotection, empêchant ainsi les spires de l'enroulement de former un circuit ouvert.
