Description
Les alimentations DC dynamiques de la série N7900 sont conçues pour les applications d'équipement de test automatisé (ATE) où une source et une mesure dynamiques à haute vitesse sont nécessaires.
Transformez n'importe quelle alimentation APS non seulement en source mais aussi en charge, ce qui est idéal pour les applications de stockage d'énergie.
Logiciel BenchVue activé. Faites-en plus avec votre PC et votre instrument ensemble, sans programmation requise. Contrôlez facilement vos alimentations pour définir des paramètres et construire rapidement des tests automatisés sur votre PC.
Vous pouvez notamment ajouter des fonctions avancées d'affichage, de configuration et de mesure en téléchargeant le logiciel gratuit APS Power Assistant de Keysight.
