Samlex America

Samlex America IDC-100A-12 100W DC-DC Converter 9-18V Input

SKU CH-7GWX-BG3D8

A fully isolated 100 W DC-DC converter that steps 9-18 V input to a regulated 12.5 V output at 8 A, with short-circuit, over-temperature.

  • Galvanic isolation protects sensitive loads
  • 100 W output powers 12.5 V equipment
  • 2–18 V input suits 12 V vehicle systems
  • EMI/EMC compliant to EN50081-1 and EN50082-1
  • Compact 15.2 × 8.9 × 4.8 cm housing fits tight spaces

Isolated DC-DC converter for 12 V systems

The Samlex America IDC-100A-12 is a 100 W fully isolated switching converter that delivers a regulated 12.5 V output at up to 8 A from a 9.2–18 VDC source. It suits mobile, marine or industrial installations where galvanic separation between the battery and the load is required.

Input range and protection limits

The unit accepts 9.2 to 18 VDC and provides fold-back current limiting plus protection against short circuit, overheating, overvoltage and reverse-polarity connection. EMI and EMC compliance follows EN 50081-1, EN 50082-1 and automotive directive 95/54/CE, so electrical noise stays within approved bounds.

Output capacity and headroom

At 18 V input the converter supplies a continuous 8 A, giving 100 W of usable power for 12 V loads such as lighting, communications gear or instrumentation. When input voltage drops toward the lower end the available current falls accordingly, so the installer must verify that the source remains high enough for the connected equipment.

Questions about this item

Is the 100 W IDC-100A-12 the only model in this series, or are there other output-voltage versions?

The IDC-100 series includes multiple isolated converters; this IDC-100A-12 delivers 12.5 V at 8 A, while other models in the line provide different output voltages for the same 9-18 V input range.

What does the 100 W rating mean when the converter is installed in a vehicle with a 12 V battery?

At 12 V input the unit can supply its full 100 W continuously, giving a regulated 12.5 V output at up to 8 A with fold-back current limiting and short-circuit protection.

Which standards does the EMI/EMC compliance cover, and what does that limit in practice?

The converter meets EN50081-1 for emissions, EN50082-1 for immunity and automotive directive 95/54/CE, so conducted and radiated noise stay within European vehicle limits.
