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.
