L\u2019Aim-TTi EL303R est un alimentateur de puissance DC \u00e0 r\u00e9gulation lin\u00e9aire pr\u00e9cis \u00e0 sortie unique fournissant 90 W, avec une plage de sortie de 0 \u00e0 30 V et jusqu\u2019\u00e0 3 A. Il combine une r\u00e9gulation lin\u00e9aire \u00e0 faible bruit avec une excellente r\u00e9gulation de la ligne et de la charge, un fonctionnement \u00e0 tension constante ou \u00e0 courant constant et un crossover automatique. L\u2019EL303R dispose de commandes de tension grossi\u00e8re et fine, d\u2019un contr\u00f4le de courant logarithmique unique, d\u2019un contr\u00f4le local ou distant commutable pour une r\u00e9gulation pr\u00e9cise de la charge, et d\u2019un interrupteur de sortie DC \u00e9lectronique permettant de pr\u00e9configurer les valeurs de tension et de courant avant l\u2019alimentation en charge. Ses indicateurs LED \u00e0 quatre chiffres \u00e0 14 mm fournissent une r\u00e9solution de tension de 10 mV et de courant de 1 mA, tandis que les bornes de sortie acceptent des prises de 4 mm \u00e0 enveloppe fixe, des prises de 4 mm standard, des bornes \u00e0 fourche et des fils nus. Avec une imp\u00e9dance de moins de 1 mV rms et un bruit typiquement faible, une ventilation sans ventilateur et un bo\u00eetier compact de 140 \u00d7 160 \u00d7 295 mm, le EL303R convient aux applications de pr\u00e9cision sur bancs d\u2019essai n\u00e9cessitant une r\u00e9gulation lin\u00e9aire \u00e0 faible bruit et une puissance de sortie allant jusqu\u2019\u00e0 3 A.<\/p>","protected":false},"excerpt":{"rendered":"
