Available now at Dengrove Electronic Components, RECOM RP40Q-RUW and RP60Q-RUW DC/DC converters are railway certified.

The DC/DC converters serve a wide range of rolling-stock applications, as well as high-voltage battery-powered systems with their ultra-wide 14V-160V DC input-voltage range.

The single-output 40W and 60W quarter-brick converters accept all commonly used supply voltages, from nominal 24V DC to 110V DC. They feature basic isolation and a choice of regulated 5V, 12V, 15V, 24V, or 48V DC output, with Sense and Trim pins for adjusting the voltage by up to ±10%.

Offering high efficiency across the full input-voltage range, these converters make battery energy go further while minimising thermal challenges. They can operate at full load without forced air cooling or derating, from -40°C to 85°C (RP40Q-RUW) or 68°C (RP60Q-RUW). An optional heatsink is available, which extends the maximum temperature to 90°C and 77°C respectively.

Also featured for safety and reliability, the enclosures have threaded inserts for secure mounting to withstand high shock and vibration. The converters are certified to EN 50155 and the EN 45545-2 railway-equipment fire-safety standard, in addition to EN 55032 and EN 55024 EMC and electromagnetic-immunity standards. EN 60950-1, and the incoming EN 62368-1 hazard-based safety standard.
