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.

1. Current sinking up to 100% of rated current requires one N7909A power dissi- pater for 1 kW models and two N7909A power dissipaters for 2 kW models. 2 kW models with one power dissipater can sink 50% of their rated current.
2. From 20 Hz to 20 MHz.
3. Expressed as % of setting (or % of measurement) + offset. At 23 °C ±5 °C after a 30-minute warm-up; measurement. NPLC=1; valid for 1 year.
4. Time to recover within the settling band following a load change from 50% to 100% of full load.
5. When sinking current, the negative current measurement ranges match the positive current measurement ranges.
6. These are supplemental characteristics
