Railway DC-DC Eval Platforms up to 240W Accommodate High-Current or High-Voltage Designs

The R-REF04-RIA12-1 and R-REF04-RIA12-2 from RECOM are complete reference designs for railway dc-dc converter applications. The R-REF04-RIA12-1 board is populated with components rated for higher dc input voltages up to 110Vdc nominal input; the R-REF04-RIA12-2 board 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 universal pinout accommodates dc-dc converters with 2"x1", quarter-brick or half-brick standard case dimensions including the entire RECOM portfolio of railway dc-dc converters up until 240W.

Summary of features:

  • Evaluation platform for railway dc-dc converters up to 240W with either high voltage (-1) or high current (-2) layouts
  • Includes RIA12 surge stopper with reverse polarity protection
  • On-board EN50121-3-2 EMC filter layout
  • Suitable for 2"x1", quarter-brick or half-brick converters
  • External hold-up capacitor
  • Cage clamp terminals, isolated enable and fan connectors

The reference designs, samples of dc-dc converters and OEM pricing are available from all authorized distributors or directly from RECOM.
