3 W12 VDC250 mAisolated AC-DC module85–305 VACSIP module

LS03-13B12R3 is a 3 W isolated AC-DC module providing 12 VDC at up to 250 mA from a wide 85–305 VAC or 100–430 VDC input range.

Best for

  • Low-power industrial control supplies
  • Power meter and instrumentation auxiliary rails
  • Smart-home control electronics requiring isolated 12 VDC

Avoid if

  • Applications requiring more than 250 mA at 12 VDC
  • Systems that require hot-plug operation
  • Designs without space for specified external input and output components

Check before use

  • Confirm derated output power at the actual ambient temperature and input voltage
  • Fit the required 1 A / 300 V slow-blow fuse and 14D561K MOV
  • Use the specified external capacitor and output inductor network
  • Validate creepage, clearance, EMC, and surge protection in the final system
