The 30W units also meet the requirements of EN50155 for electronic equipment used on railway rolling stock.
The DCR 30R railway converters offer wide input ranges of 24VDC (15-34V), 48VDC (29-67V), 72VDC (43-101V) or 110VDC (66-154VDC). The units deliver outputs of 12, 24V or 48VDC. Custom input and output voltages are available on request. Efficiency is a minimum of 85% at full load. Heavy filtering on the input and output ensures that the units comply with EN50121-3-2. Electronic protection includes 3kVDC input to output isolation, inrush current limiting and reverse polarity protection, current limiting, overload, overvoltage and short circuit protection.
Cooling is by conduction via baseplate, with additional cooling by natural convection. The converters operate within a -25 to 55°C cold plate temperature range for full specification, without the need for derating. Wider temperature ranges are available on request.
