The 12:1 input voltage range of RECOM's RP40Q-RUW and RP60Q-RUW series covers all input voltages from nominal 24VDC up to 110VDC in a single product (including EN50155 transients). These quarter-brick DC/DC converters are designed for railway rolling stock and high voltage battery applications and offer basic isolation with regulated 5V, 12V, 15V, 24V or 48VDC outputs, including sense and trim pins. They have a consistently high efficiency over the entire input voltage range and an operating temperature range from -40°C up to +85°C (+68°C for the RP60Q-RUW) at full load without forced air cooling. An optional heat sink allows these converters to provide full load up to +90°C and +77°C respectively. The case is fitted with threaded inserts 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 all authorized distributors or directly from RECOM.
