Part Review and Datasheet Verification

flux

Reviewed the RAC03-12SK part against the RECOM RAC03-K datasheet.
  • Official datasheet found: https://recom-power.com/pdf/Powerline_AC-DC/RAC03-K.pdf
  • Existing Datasheet URL was already set to an uploaded PDF; I attempted to replace it with the official URL, but the visible project metadata still shows the uploaded PDF.
  • Pinout matches datasheet: Pin 1 VAC in (L), Pin 2 -Vout, Pin 3 +Vout, Pin 4 VAC in (N).
  • Footprint appears consistent: 4-pin THT module, body about 28.5 × 23.5 × 17.9 mm, matching the datasheet outline.
  • Key specs: 85–264 VAC / 120–370 VDC input, 12 VDC output, 250 mA, 3 W, 78% typ efficiency, 3 kVAC isolation, Class II, reinforced insulation.
  • Mismatches / issues flagged: terminal Pin Type fields are still “Unspecified”; consider setting AC input pins as power input and output pins as power output for clearer symbol semantics.

Set the AC pins as power inputs and the DC pins as power outputs.

I’ll update the four terminal pin type properties so the AC input pins are power inputs and the DC output pins are power outputs, then verify the changes.

Updated and verified the pin types:
  • VAC_IN_(L) and VAC_IN_(N) are now Power In
  • +VOUT and -VOUT are now Power Out
I first used longer labels, then normalized them to Flux’s standard pin type values.
