L\u2019Aim-TTi EX354RD est un alimentateur de puissance DC \u00e0 mode mixte \u00e0 deux sorties, fournissant une puissance totale de 280 W, avec deux sorties ind\u00e9pendantes et isol\u00e9es, chacune offrant une tension de 0 \u00e0 35 V \u00e0 une puissance maximale de 4 A. Il combine une pr\u00e9-r\u00e9gulation par commutation avec une r\u00e9gulation finale lin\u00e9aire 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 fonctionne en mode tension constante ou courant constant avec un crossover automatique et comprend des commandes de tension grossi\u00e8re et fine, un contr\u00f4le de courant logarithmique, un commutateur \u00e9lectronique de sortie CC et un capteur local ou distant. Les deux sorties peuvent \u00eatre connect\u00e9es en s\u00e9rie pour fournir jusqu\u2019\u00e0 70 V ou en parall\u00e8le pour fournir jusqu\u2019\u00e0 8 A. Les indicateurs de tension et de courant LED \u00e0 quatre chiffres de 14 mm permettent de mesurer simultan\u00e9ment la tension et la puissance avec une r\u00e9solution de 10 mV pour la tension et 1 mA pour la puissance, tandis qu\u2019une protection contre les courts-circuits, les tensions externes et les courants inverses est assur\u00e9e. La technologie de refroidissement par convection sans ventilateur ainsi que l\u2019enceinte compacte de 260 \u00d7 160 \u00d7 320 mm en font un appareil adapt\u00e9 aux applications de banc d\u2019essai n\u00e9cessitant une puissance de sortie double, associ\u00e9e \u00e0 une faible consommation d\u2019\u00e9nergie et une grande efficacit\u00e9.<\/p>","protected":false},"excerpt":{"rendered":"
