Abstract
L'alimentation du capteur D et des organes auxiliaires est obtenue, à partir du pont redresseur 3-4-5-6, au moyen de deux circuits régulateurs dont le premier fonctionne lorsqu'un transistor inhibiteur 35 est passant, tandis que le second fonctionne lorsque le transistor inhibiteur est bloqué. Le premier circuit régulateur est du type à ballast (résistances 16, 17, 23; diode Zener 18, transistor d'excitation 26 et thyristor ballast 19). Le second circuit régulateur (diode 32 et diodes de Zener 31 et 33) est du type engendrant un retard à l'amorçage du thyristor de commutation 9. Application aux détecteurs alimentés par une tension alternative variable dans une large gamme.
