Abstract
Moniteur de service dans lequel un détecteur de surtension 14 génère un signal d'interruption lorsque la crête de la tension d'entrée dépasse un seuil. Le signal d'interruption est annulé lorsque la crête descend d'une certaine quantité au-dessous du seuil. Un détecteur de sous-tension 24 génère un autre signal d'interruption de façon analogue. Un registre 40 mémorise plusieurs cycles de la tension d'entrée avant et après chaque interruption. Application à la surveillance des lignes d'alimentation des unites de traitement de données.
