<\/i>Charge Active 40A<\/h3>\n <\/div>\n
\n \n

Cet appareil est destiné à tester les alimentations  basse tension.<\/h4>\n

Il remplace avantageusement les résistances de puissance que l’on utilise habituellement pour tester la régulation ou la limitation en intensité d’une alimentation. Le mode Modulé permet une analyse du comportement en dynamique. <\/p>\n

Pour une utilisation sans risque de ce dipositif  merci de prendre contact avec le concepteur Thierry A.<\/h3>\n

Le commutateur de fonctions comporte trois positions.<\/h4>\n

1 – Résistance constante<\/h4>\n

La tension de référence permettant d’obtenir la tension de consigne est la tension d’entrée donnée par l’alimentation sous
test. Si cette dernière varie, la consigne varie, entraînant une variation de courant dans les mêmes proportions : DU \/ DI =
R. La charge se comporte comme une résistance de valeur fixe, choisie par les potentiomètres de consigne.<\/p>\n

2 – Courant constant<\/h4>\n

La tension de consigne est fixée par une référence de tension constante. Le courant imposé par la charge à l’alimentation
sous test est donc constant, et indépendant de la tension présentée par celle-ci.
Un voltmètre connecté à la prise BNC située dans la partie inférieure droite de la face avant, permet de régler, si besoin, le
débit avant que l’alimentation sous test ne soit raccordée. La tension sur cette sortie représente le débit au taux de 5 A \/ V.
Un commutateur et deux prises 2mm permettent d’effectuer la mesure de la tension aux bornes de l’alimentation sous
test, la chute de tension dans les câbles de liaison étant ainsi ignorée.<\/p>\n

3 – Courant modulé<\/h4>\n

La tension de consigne est prélevée à la sortie d’un générateur pouvant délivrer un signal rectangulaire ou triangulaire.
Trois potentiomètres déterminent son amplitude, son offset et sa fréquence. Un oscilloscope connecté à la prise BNC
inférieure droite permettra de visualiser le régime du débit imposé à l’alimentation sous test (toujours au taux de 5A \/ V)
avant la connexion de celle-ci. A noter que les potentiomètres de consigne sont toujours actifs dans cette
configuration.
La visualisation de la variation DU de la tension présentée par l’alimentation sous test permettra, pour un DI connu, de
calculer sa résistance dynamique r = DU \/ DI, ainsi que d’apprécier le comportement de sa régulation
(suroscillations, overshoot, etc).<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n \n","protected":false},"excerpt":{"rendered":"","protected":false},"author":89,"featured_media":306,"parent":111,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"page-le.php","meta":{"footnotes":""},"class_list":["post-301","page","type-page","status-publish","has-post-thumbnail","hentry"],"yoast_head":"\nCharge Active -
