Description
The RAC20-N series is a universal-input, board-mounting AC/DC module that delivers 20W in a
compact 2” x 1” footprint. The converter is pin-compatible with the RAC05-SC, RAC10-SC and
RAC20-SB models, offering a simple power upgrade or a cost-down option without requiring any PCB
changes.
