Alimentation impulsionnelle de 500A sous 100V
2 canaux indépendants de 500 A - 100 V crête
Alim. impulsionnelle pour diodes QCW
L’alimentation en courant génère des impulsions réglables de 0 à 500 A sous 100 V. La durée d’impulsion est réglable de 20 µs à 3 ms. La puissance moyenne délivrable est de 1000 W au total. Elle se présente sous un format 3U, comprenant le convertisseur AC/DC et 2 générateurs d’impulsions indépendants. Enfin l’alimentation se pilote via une interface de type écran tactile et bus Ethernet.
- Fiable, utilisant des composants industriels
- Entrée 115-230 VAC / 50-60 Hz
- Tension délivrée aux diodes : 0 à 100 V
- Sorties de type flottant
- 1 ou 2 canaux en option, indépendants (2x500 A) ou en parallèle (1x1000 A)
- Haute efficacité : 80% typique
- Protection en surtension, surintensité, court-circuit ou circuit ouvert
- Fonctions écran: paramètres de l’impulsion, seuil de sécurité, mesures et code d’erreurs
- Interface de communication : I2C, SPI, CAN or Ethernet
