RECOM PowerlinePLUS DC/DC converters

RECOM has extended its PowerlinePLUS-family of DC/DC converters with the RPR-series, specifically tailored to railway applications. The compact devices work under extreme operating conditions without derating and are designed for input voltages of up to 160 DC.

The new converters work with full power at operating temperatures of -45 to >+85°C without derating (Tx). The efficiency is >89%. They are robust and EN61373 tested for 10 G shock and vibration in all three axes. The series is power rated with 20, 30, 40 and 50 W and cover a wide input voltage range of 12 to 36, 25 to 75 and 40 to 160 DC. Single output voltages of 3.3, 5, 12, 15 and dual output voltages of ±12, ±15 and ±24 VDC are available.

The converters are available in three different case styles: the ‘ribbed case’ with integrated heat sink is suitable for PCB mounting with convection cooling; the ‘flat case’ version, useful in low profile applications with limited headroom; and the ‘base plate case’ version, where the converters are screw mounted to the frame for mechanical stability.

The RPR-converters are EN50155 and EN60950-1 compliant and have 1.6 kV/1 min. isolation as standard. They have integrated EMC filters to EN50121-3-2, so a complete power supply can be built using only a few external components.
