Abstract

UN TRANSISTOR MOS T1 CON DRENADOR CONECTA UN BORNE 15 DEL DETECTOR CON UNA ENTRADA DE CONTROL DEL INTERRUPTOR DE POTENCIA 30 MEDIANTE UN INTERRUPTOR PILOTO T2. SE ACOPLA UNA ETAPA REGULADORA 45 A T1 PARA MANTENERLO SATURADO EN EL ESTADO CERRADO DEL DETECTOR; EN ESTA SITUACION, T2 ESTA EN CONDUCCION Y, PARA REGULAR SU TENSION DE REJILLA EN EL ESTADO ABIERTO DEL DETECTOR, T2 SE BLOQUEA.
