FAQ
UPS signifie Uninterruptible Power Supply (alimentation sans interruption) et est un dispositif qui fournit une alimentation continue pour protéger les charges critiques contre les pannes ou les fluctuations de courant.
Le rôle principal d'une ASI est de fournir une source d'alimentation de secours afin que les équipements critiques puissent continuer à fonctionner lorsque l'alimentation électrique est interrompue ou instable, évitant ainsi la perte de données ou l'endommagement de l'équipement.
L'UPS se divise principalement en trois types : hors ligne, en ligne et interactif en ligne.
Lors du choix de la puissance de l'onduleur, vous devez tenir compte de la demande totale de puissance de la charge. Il est généralement recommandé de choisir une puissance légèrement supérieure à la puissance totale de la charge de l'onduleur afin de garantir un temps de veille suffisant.
Le temps de veille d'une ASI dépend de la capacité de la batterie et de la puissance de la charge. Le temps de veille varie généralement de 10 minutes à plusieurs heures, et les besoins spécifiques peuvent être déterminés en fonction du scénario d'application réel.
