Description
The QM48T/S14120 converter of the QM-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 QM-Series converters provide outputs that can be trimmed from –20% to
+10% of the nominal output voltage, thus providing outstanding design flexibility.
The paralleling version of the QM48T/S14120-wxyP converter has the paralleling capability for use in applications
requiring higher power levels than available with a single converter.
