Die TBOH02 ist eine pr\u00e4zise, selbstversorgte aktive Last. Sie ben\u00f6tigt keine separate Versorgungsspannung und arbeitet bereits ab 2V. Sie zeichnet sich durch konstanten Widerstand und Konstantstrombetrieb aus. Ein 10-Gang-Potentiometer mit Skala, ein Messbereichsschalter und eine Pr\u00e4zisionsreferenz erm\u00f6glichen die genaue Einstellung von Strom oder Widerstand. Au\u00dferdem kann es durch eine externe Spannung gesteuert werden. Das Design ist vollst\u00e4ndig analog, was weitestgehend verhindert, dass die Last selber leitungsgebundene St\u00f6rungen einspeist, die meist auf die digitalen Komponenten zur\u00fcckzuf\u00fchren sind. Die TBOH02 kann nicht nur als aktive Last f\u00fcr Stromversorgungsmessungen verwendet werden, sondern auch als Stromsenke oder Stromquelle f\u00fcr Power-LED-Tests und \u00e4hnliche Anwendungen. Auch bei Tests im Feld, wo keine externe Stromversorgung zur Verf\u00fcgung steht, ist sie hilfreich. Die TBSOH02 arbeitet von 2V bis 70V. Der maximale Strom betr\u00e4gt bis zu 10A, jedoch ist darauf zu achten, dass die maximale Leistung ohne zus\u00e4tzliche K\u00fchlung auf 25W begrenzt ist. Ein auf den K\u00fchlk\u00f6rper aufsteckbares L\u00fcfterzubeh\u00f6r erh\u00f6ht die maximale Leistung auf 100W. Die Konstruktion basiert auf dem Artikel EDN, August 2005 Pr\u00e4zisions-Wirklast von Joel Setton. Mit freundlicher Genehmigung von Joel Setton, Crolles, Frankreich. Hier wieder ein Super Test der TBOH02 von unserem Freund Dave vom EEVblog.<\/p>\n","protected":false},"excerpt":{"rendered":"
