DC/DC Converters for Rail Applications
Over the years, RECOM has expanded its portfolio of DC/DC converters for the railway industry from 8W to 240W and can now offer the broadest portfolio of EN50155 certified products available on the market.
The railway-certified series pack up to 240W in compact case sizes for a power density of up to 4.5W/cm³ - one of the highest available on the market. For superior thermal performance, RECOM also offers the 12W RP12-AR, 20W RPA20-AW and 30W RPA30-AW series in a 1”x1” case and the 60W RPA60-FW series in a 2”x1” case.
These regulated DC/DC converters with their 4:1 wide input voltage range are specially designed for railway applications. The RPA100H and RPA200H series even offer an impressive 10:1 input voltage range to cover all input voltages from nominal 24VDC up to 110VDC in a single product. The RP40Q-RUW and RP60Q-RUW series even go beyond that and accept 12:1 inputs.
All series are EN50155 certified* and designed for use in harsh environments or on rolling stock. Since they are UL/cUL60950 certified, they are also a reliable choice for industrial and telecommunication applications.
"RECOM introduced evaluation platforms for its DC/DC railway converters up to 240W. They are available in either high voltage (-1) or high current (-2) layouts and include a RIA12 surge stopper.
R-REF04-RIA12.
The RSPxxx-168 are surge protectors designed to protect railway DC/DC converters from excessive voltage surges of up to 385VDC.
Besides 3.3V, 5V, 12V and 15V single outputs, dual ±12V and ±15V outputs are available. The control pin logic can be chosen to be positive or negative. With efficiencies of up to 93%, cooling by natural convection is typically all that is needed, but if required, the modules are also available with a pre-mounted heatsink. The modules come with RECOM’s standard 3 year warranty.
