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 EN 45545-2 and EN 50155 compliant, as well as for UL/IEC/EN 62368-1 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 EN 45545-2 for fire protection, EN 60068-2-1 for dry and damp heat and EN 61373 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.
