Evaluation platforms for dc/dc railway converters up to 240 W are available in either high voltage (-1) or high current (-2) layouts and include a RIA12 surge stopper.
The R-REF04-RIA12-1 and R-REF04-RIA12-2 are complete reference designs for railway applications. The 
R-REF04-RIA12-1 board is populated with components rated for higher dc input voltages up to 110 Vdc nominal input; the R-REF04-RIA12-2 board is populated with components rated for higher dc input currents up to 10 A. Both boards are input-side fused and can be used with dc/dc converters with single output currents up to 45 A.
The reference designs include a RIA12-conform surge stopper capable of blocking surge voltages up to 385 Vdc. The universal pinout accommodates dc/dc converters with 2×1-in, quarter brick or half brick standard case dimensions including the entire RECOM portfolio of railway dc/dc converters up until 240 W. The reference designs, samples of dc/dc converters and OEM pricing are available from all authorized distributors or directly from RECOM.
