Description
The QME48T40050 converter of the QME-Series provides outstanding thermal performance in high temperature
environments. This performance is accomplished through the use of patented/patent-pending circuits, packaging,
and processing techniques to achieve ultra-high efficiency, excellent thermal management, and a low-body profile.
The low-body profile and the preclusion of heat sinks minimize impedance to system airflow, thus enhancing
cooling for both upstream and downstream devices. The use of 100% automation for assembly, coupled with
advanced electronic circuits and thermal design, results in a product with extremely high reliability.
Operating from a 36-75 V input, the QME-Series converters provide outputs that can be trimmed from –20% to
+10% of the nominal output voltage, thus providing outstanding design flexibility.
