Abstract

Una fuente de alimentación de corriente eléctrica para un aparato funcional, más particularmente un aparato de seguridad, tal como un dispositivo para detección de pérdidas a tierra, el cual aparece ha de ser conectado con una instalación eléctrica que tiene un electrodo de tierra asociado con él y ha de ser abastecido a partir de las líneas de fase y de neutro de una red de distribución de corriente alterna, estando provisto dicho manantial de energía con un circuito rectificador que tiene terminales primero, segundo y tercero que sirven para su conexión, respectivamente, con las líneas de fase y de neutro de la red de distribución y con el electrodo de tierra, de manera que el circuito rectificador es abastecido a través del electrodo de tierra al menos en el caso de una rotura en la línea de neutro o en un conductor que conecta a este último con el circuito rectificador, caracterizada porque el tercer terminal está conectado con el primer circuito rectificador a través de un segundo circuito rectificador.
