12:1 input for railway dc-dc PSU


“The input voltage range covers all input voltages from nominal 24Vdc up to 110Vdc in a single product, including EN50155 transients making them a universal solution for railway rolling stock applications and high voltage battery systems,” said the firm.

The supplies are the 40W RP40Q-RUW and the 60W RP60Q-RUW.

Outputs are isolated, and different versions give regulated options of 5, 12, 15, 24 or 48Vdc – with outputs including sense and trim pins.

Operation is over -40°C up to +85°C for the 40W type and up to 68°C for the RP60Q-RUW at full load without forced air cooling, then an optional heat sink takes full load operation up to 90°C and 77°C respectively.

Threaded inserts are fitted into the case for secure mounting in high shock and vibration environments.

The converters are CE marked, EN50155 and EN45545-2 certified and come with a three-year warranty.

Samples and OEM pricing are available from authorided distributors or directly from Recom.
