The RPR20 series DC/DC converters are designed for railway rolling stock applications.
Besides covering all the input voltages from 24VDC up to 110VDC, the converters have a
very wide operating temperature range of -45°C to +85°C without derating. Although the
case size is very compact, the converter contains a built-in EMI filter, so no active external
filter components are required. The RPR20 is available in three case styles: a low profile flat
top case, a ribbed case with a built-in heatsink and the baseplate case for high vibration or
bulkhead mounting applications. They are EN 50155 and EN 50121-3-2 compliant.
