Description
Le module d'alimentation TestScale est équipé d'une alimentation programmable capable de fournir une gamme complète de courants et de tensions, ainsi que d'une fonction de lecture à distance à boucle fermée et de protections contre les surtensions, les surintensités et les surtempératures. Ce module est compatible avec les distributions Linux courantes et peut être intégré aux logiciels NI tels que TestStand, LabVIEW et SystemLink. De plus, il est livré avec le driver NI-DAQmx, qui comprend un exemple de code et prend en charge les langages courants comme Python, C/C++, .NET et LabVIEW.
- Les conditions typiques d'utilisation sont une température ambiante de 0°C à 55°C, mesurée à l'entrée d'air du ventilateur de l'enceinte.
- Pour plus d'informations sur les caractéristiques de température ambiante et les exigences de refroidissement, consultez le manuel utilisateur TestScale sur ni.com/docs.
- Les spécifications de température pour chaque module individuel sont également disponibles.
- Un temps de préchauffage de 15 minutes est nécessaire.
- Toutes les tensions sont relatives à la masse (GND).
