L\u2019Aim-TTi EX354RT est un convertisseur de tension continue \u00e0 trois sorties \u00e0 mode mixte fournissant une puissance nominale totale de 305 W, avec deux sorties principales offrant respectivement 0 \u00e0 35 V \u00e0 une puissance maximale de 4 A, ainsi qu\u2019une sortie auxiliaire variable r\u00e9glable entre 1,5 et 5,0 V \u00e0 une puissance maximale de 5 A. L\u2019EX354RT combine une pr\u00e9-r\u00e9gulation par commutation avec une r\u00e9gulation lin\u00e9aire de la sortie pour offrir une efficacit\u00e9 \u00e9lev\u00e9e, un faible bruit, une excellente r\u00e9gulation de la ligne et de la charge, ainsi qu\u2019une bonne r\u00e9ponse aux changements de tension. Chaque sortie principale permet une alimentation \u00e0 tension constante ou \u00e0 courant constant avec un crossover automatique, des commandes de tension grossi\u00e8re et fine, un contr\u00f4le du courant logarithmique, une d\u00e9tection locale ou \u00e0 distance commutable et un commutateur de sortie DC \u00e9lectronique avec des limites de tension et de courant pr\u00e9d\u00e9finies affich\u00e9es lorsque la sortie est d\u00e9sactiv\u00e9e. Les deux sorties principales peuvent \u00eatre connect\u00e9es en s\u00e9rie pour une puissance maximale de 70 V ou en parall\u00e8le pour une puissance maximale de 8 A. Les quatre m\u00e8tres de tension et de courant \u00e0 quatre chiffres ind\u00e9pendants fournissent une r\u00e9solution de 10 mV pour la tension et 1 mA pour la puissance, tandis que la sortie auxiliaire offre une limite de courant fixe de 5 A avec une tension r\u00e9glable mesurable \u00e0 l\u2019aide des m\u00e8tres num\u00e9riques. Toutes les sorties sont prot\u00e9g\u00e9es contre les courts-circuits, gr\u00e2ce \u00e0 un refroidissement par convection sans ventilateur et \u00e0 un bo\u00eetier compact de 260 \u00d7 160 \u00d7 320 mm, ce qui rend l\u2019EX354RT adapt\u00e9 aux applications de banc d\u2019essai n\u00e9cessitant plusieurs sorties \u00e0 faible bruit.<\/p>","protected":false},"excerpt":{"rendered":"
