By RECOM Power 57
RECOM Power's RPA100H and RPA200H series half-brick DC/DC converters are designed for railway rolling stock and high voltage battery applications. When planning a universally applicable railway device at least three versions of the same design are typically necessary to cover all standard supply voltages in railway vehicles ranging from a nominal 24 VDC to 110 VDC. This causes additional complications that can be avoided by using RECOM’s DC/DC railway converters with ultra-wide input voltage, which allow for all-in-one solutions.
By accepting a 10:1 input voltage from 14.4 VDC to 156 VDC, these converters can be considered for any railway design without worrying about voltage tolerances, voltage dips, or the local supply voltage. Their ultra-wide input voltage range covers all standard battery supply voltages from 24 VDC to 110 VDC (including EN50155 transients and brownouts) in a single product and they offer isolated and regulated 12 V or 24 VDC outputs.

Continuous full power operation is certified between 16.8 V and 137.5 V, including full load start-up. Once running, the converter will operate for short periods of time over an extended input voltage range down to 14.4 V and up to 156 V, thus covering all EN50155 undervoltage and overvoltage transient conditions. |

The converters have a consistently high efficiency over the entire input voltage and load range, and come with a metal baseplate to permit a wide operating temperature range from -40°C up to +97°C (when suitably cooled). For high reliability, no tantalum capacitors are used internally and the casing has threaded inserts to allow secure mounting to PCBs or bulkheads for use in high shock and vibration environments. The converters are fully compliant to EN50155, certified to UL/IEC/EN60950 and come with a three-year warranty. |
