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.
