DESCRIPTION
The QAW series of DC/DC converters offers 40 watts of output power and has an ultra wide input range of 9 – 36VDC and
18 – 75VDC. This series also has single, dual, and triple output models. Some features include remote on/off control,
adjustable outputs, thermal overload protection, over voltage protection, and short circuit protection. The QAW series allows
higher power density with higher efficiency, while maintaining an industry-standard pinout configuration. With this series, the
designer can retrofit the converter on existing designs as well as making use of the smaller package size on new designs. All
models are 100% burn-in tested.
