The RPR50 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. Although the case size is very
compact, the converter contains a built-in Class A EMI filter, so few external components are
required. The RPR50 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.
