RECOM has launched an eighth-brick DC/DC converter series with 9-60 VDC input and optional 12, 24, or 48 V outputs rated at 150 W. The RPA150E series has an industry-standard pin-out with outputs trimmable over a wide ±20% range to include 28 V for avionic systems and 57 V for PoE applications.
The 6:1 input range covers nominal 12, 24, and 48 V system rails with sufficient margin to include 48 V battery charging voltage and 12 V battery cranking voltage dips.
High efficiency of the RPA150E series
The efficiency of the RPA150E series is high, up to 92% typical, allowing operation to +85°C with minimal derating with airflow or baseplate cooling. Isolation is rated at 3 kVDC, and standard control and protection features include remote on/off, under-voltage lockout, over-voltage, over-current, and over-temperature.
EN 50121-3-2 railway EMC standards
Safety certifications for the converter include UL 62368-1, CAN/CSA-C22 No. 62368-1, and the parts are EMC-compliant to EN 55032 and EN 55011 with a recommended external filter network. With suitable external components, the RPA150E series is compliant with EN 50155 and EN 45545-2 railway functional and safety standards along with EN 50121-3-2 railway EMC standards.
Matthew Dauterive, DC/DC Product Manager of RECOM, comments: “The wide input range of our RPA150E series means it can provide cost-effective power conversion from battery voltages in EVs, rail, and E-mobility designs, as well as in a broad range of industrial applications.”
