RECOM Power R-REF04-RIA12 Reference Designs

RECOM Power R-REF04-RIA12 Reference Designs feature a universal pinout to accommodate DC/DC converters with 2" x 1", quarter-brick, or half-brick standard case dimensions. RECOM Power R-REF04-RIA12-1 is populated with components rated for higher DC input voltages up to 110VDC nominal input, while the R-REF04-RIA12-2 is populated with components rated for higher DC input currents up to 10A. Both boards are input-side fused and can be used with DC/DC converters with single output currents up to 45A. The reference designs include a RIA12-conform surge stopper capable of blocking surge voltages up to 385VDC. The reference designs are ideal for railway applications.
