Quarter-brick DC/DC Converter Series

Powerbox releases three new DC/DC converters, the PQAE40U (40W), the PQAE60U (60W) and the PQAE100U (100W), with an extra wide input voltage range of 14V to 160V and 9V to 75V (for lower bus voltages). These board-mounted converters for the railway, transportation and defense industries provide systems designers with a single part number that allows to power applications such as industrial automation and automotive or remote radio-control in order to reduce inventory, time to market and documentation. They meet thermal shock and vibration requirements (EN61373 and MIL-STD-810F), and also fire and smoke EN45545-2 standard.


All units include continuous operation in the 14.4V brownout condition and 154V transients


Operating from -40 to +105°C, they suit demanding, ruggedized requirements such as in construction vehicles, mining equipment and heavy machinery process control. The PQAE40/60/100U series is available in seven output voltages of 5, 12, 15, 24, 28, 48 and 53V, and features an efficiency figure of up to 90%. They come with full protection level sets including over voltage, short-circuit, overload protection and thermal shutdown. All models are RoHS compliant and are housed in a plastic case with an aluminum baseplate and are potted with a UL94-V0 silicon compound.
