Abstract

L'invention concerne une source d'alimentation pour un appareil fonctionnel de faible consommation d'énergie. Cette source d'alimentation comporte un premier circuit redresseur alimenté normalement par les conducteurs de phase et de neutre d'une distribution de courant alternatif du secteur, et un second circuit redresseur alimenté entre l'un de ces conducteurs et une prise de terre dans le cas d'une interruption du conducteur neutre. L'appareil peut ainsi continuer à fonctionner dans le cas d'une rupture d'un conducteur neutre. L'invention s'applique notamment à l'alimentation d'un dispositif de détection de fuite à la terre.Provided is a power source for a functional apparatus of low power consumption. This power source comprises a first rectifier circuit supplied normally by the phase and neutral conductors of an alternating current distribution of the sector, and a second rectifier circuit supplied between one of these conductors and an earth electrode in the mains. case of an interruption of the neutral conductor. The device can thus continue to operate in the event of a break in a neutral conductor. The invention applies in particular to the power supply of an earth leakage detection device.
