L\u2019Aim-TTi LD400P est un chargeur \u00e9lectronique DC programmable de 400 W con\u00e7u pour tester et caract\u00e9riser une large gamme de sources d\u2019alimentation DC, notamment les batteries, les cellules solaires et les alimentations \u00e9lectroniques. Il offre une plage de fonctionnement allant de 0 \u00e0 80 V et de 0 \u00e0 80 A, avec une dissipation de puissance continue allant jusqu\u2019\u00e0 400 W \u00e0 28 \u00b0C et une dissipation \u00e0 court terme allant jusqu\u2019\u00e0 600 W pendant 60 secondes. L\u2019LD400P prend en charge les modes de fonctionnement \u00e0 courant constant, r\u00e9sistance constante, conductance constante, tension constante et puissance constante, avec un r\u00e9glage de niveau de r\u00e9solution \u00e9lev\u00e9 et une tension de fonctionnement minimale basse qui reste inf\u00e9rieure \u00e0 1 V jusqu\u2019\u00e0 40 A. Son g\u00e9n\u00e9rateur transitoire int\u00e9gr\u00e9 offre des fonctions de contr\u00f4le de fr\u00e9quence variable, de d\u00e9phasage et de d\u00e9calage, tandis qu\u2019une sortie de contr\u00f4le de courant permet de visualiser les formes d\u2019onde et une tension de d\u00e9connexion variable permet d\u2019effectuer des tests sur les batteries. Un LCD r\u00e9tro\u00e9clair\u00e9 haute r\u00e9solution avec contr\u00f4le par touches permet une utilisation locale, tandis que le contr\u00f4le analogique \u00e0 distance et le contr\u00f4le TTL permettent une utilisation externe. Un contr\u00f4le \u00e0 distance complet et un retour d\u2019information sont fournis via des interfaces USB, RS-232 et LAN conformes \u00e0 LXI, avec une option pour une connexion GPIB. Des bornes d\u2019entr\u00e9e frontales et arri\u00e8re, une d\u00e9tection de tension externe et un refroidissement par ventilateur \u00e0 vitesse variable permettent une utilisation flexible du syst\u00e8me, tandis que son bo\u00eetier compact de demi-rack 3U rend le LD400P adapt\u00e9 \u00e0 l\u2019utilisation en laboratoire ou pour l\u2019essai automatis\u00e9 des sources d\u2019alimentation continue.<\/p>","protected":false},"excerpt":{"rendered":"
