QAW

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.

● 100% Burn-in ● High Efficiency ● Adjustable Outputs ● Remote On/Off Control ● Ultra Wide Input Range ● 100°C Case Temperature ● Thermal Overload Protection ● Higher Operating Temperature ● UL1950, EN60950 (see Note 8) ● Single, Dual, and Triple Outputs ● Continuous Short Circuit Protection ● Up to 1500VDC I/O Isolation Voltage ● Input Under and Over Voltage Lockout ● New 2” x 3” Package (fits 3” x 3” pin out)
