12:1 Ultra-Wide Input Range 100W DC/DC Converter for Rail Applications

by | Jan 8, 2020 | P-Duke, Press release, Rail

P-DUKE have announced their QAE100U family which expands its existing QAE series of EN50155 approved rail DC/DC converters to 100 watts of output power. Other parts in the series offer 40W and 60W variants. The letter “U” in the series name denotes its ultra-wide input range. There are versions offering an input range of 8:1 of 9-75Vdc and 12:1 of 14-160Vdc. With one single 12:1 ultra-wide input range module you can cover every kind of power system used in rolling stock applications.

The QAE100U has been specifically designed for rolling stock applications. Its 12:1 input range of 14-160Vdc can be suitable for 24, 36, 48, 72, 96, 110Vdc power system described in EN50155 and is compliant with the following safety standards of EN50155, EN45545-2, IEC60950-1, IEC62368-1, EN61373.

QAE100U provides a single output with 5, 12, 15, 24, 28, 48 or 53Vdc output voltage. It can be installed on PCB or chassis; securely by screws. There is also the option of adding a heat-sink to cope with extreme thermal demands.
