P-DUKE have announced their QAE100U family which expands its existing QAE series of rail DC/DC converters to 100 watts of output power. Other parts in the series offer 40 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 nine to 75Vdc and 12:1 of 14 to 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 to 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 five, 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.
