The MQSA-28-05S accepts a continuous input voltage of 16-40V, and it is capable of handling a transient input voltage of 50V for 1 second. This over-voltage transient complies with MIL-STD-704F, RTCA/DO-160G Cat A/R, MIL-STD-1275D (Gen+Bat), and DEF-STAN 61-5 (Part 6)/5 (Gen+Bat) limitations.

The MQSA-28-05S converter operates from -55 to 125 degrees C baseplate temperature and provides up to 5W of power at a typical 80% efficiency throughout the temperature profile. It has an input-side referenced enable, an output over-voltage protection, a continuous short circuit and overload protection, as well as input under-voltage shutdown. There are no opto-isolators in the converter.
