Component

AC/DC module5 VDC output3 W3000 VAC isolationPCB mount85–305 VAC input

LD03-23B05R2 is a 3 W isolated AC/DC PCB module for converting 85–305 VAC mains input to regulated 5 VDC at up to 600 mA.

Best for

  • Isolated 5 V auxiliary rails
  • Industrial control electronics
  • Telecom and data communication equipment

Avoid if

  • Applications requiring more than 600 mA at 5 V
  • Designs needing guaranteed full load across the entire 85–305 VAC range without derating
  • Applications requiring documented RoHS, REACH, or lifecycle status

Check before use

  • Input-voltage derating at 85–100 VAC and 240–305 VAC
  • Temperature derating above +70 °C
  • Minimum 10% output load
  • External fuse and EMC component requirements
