RECOM has achieved a new level of high-efficiency DC/DC performance in a compact 1.6” x 1” x 0.4” package (40.6mm x 25.4mm x 10.2mm). The RPA20-FR series delivers 20W over its full 36VDC-160VDC input range (200VDC peak for 1 second) from -40°C to 70°C and 105°C with derating. Fully regulated, low-noise, and protected single outputs available are 5V, 5.1V, 12V, 15V, and 24VDC, trimmable by +20%/-10% minimum, while +/-5V, +/-12V, and +/-15VDC options are also offered. Remote ON/OFF control with positive or negative logic and under-voltage lock-out is included, and no minimum load is required.

The parts are designed specifically for rolling stock applications with nominal input voltages of 48V, 72V, or 110VDC and are EN45545-2 and EN50155 compliant, as well as for UL/IEC/EN62368-1 for audio/video and IT applications. Full 3kVAC/1min reinforced isolation is provided, and the parts comply with EMC ‘Class A’ levels as well as rail EMC standard EN 50121-3-2. A separate protection module RSP150-168 is available to protect against surges according to RIA12 and NF F01-51 standards.
The RPA20-FR series meets environmental standards required for rail applications, particularly EN45545-2 for fire protection, EN60068-2-1 for dry and damp heat, and EN61373 for shock and vibration. MTBF is over 1.5Mhrs at 25°C, according to MIL-HDBK-217F, GB.
“The rail environment can be harsh, but these power-dense and reliable DC/DCs are a perfect cost-effective solution,” comments Stanislav Suchovsky, MSc. Technology Engineer of RECOM. “Their performance also makes them a good fit for other critical applications such as in industrial, energy, IT, and test and measurement”.
Parts include a three-year warranty. Samples and OEM pricing are available from all authorized distributors or directly from RECOM.
