Samlex 360W Fully Isolated DC-DC Converter - 30A - 9-18V Input - 12.5V Output

The Samlex 360W Fully Isolated DC-DC Converter is purpose-built for mobile installations where clean, regulated 12-volt power must be isolated from high-voltage primary systems—a critical requirement in modern vehicle builds, emergency response vehicles, and dual-battery setups. Whether you're running auxiliary electronics off a 24V truck system, powering sensitive avionics in an adventure rig, or isolating ground loops in a complex audio installation, this converter eliminates voltage spikes and RF noise that can damage equipment or create parasitic draws. It's the kind of component that separates professional-grade vehicle modifications from roadside failures.

The IDC-360A-12 model accepts input voltages from 9 to 18 volts and delivers a stable 12.5-volt output at up to 30 amps—providing a maximum of 360 watts of continuous power for demanding auxiliary systems. Galvanic isolation between input and output ensures that ground loops, common in vehicles with multiple battery banks or long wiring runs, are completely broken, preventing voltage spikes and protecting sensitive electronics from surges. The fully isolated topology means the converter's output shares no common ground with the vehicle chassis or primary system, a design philosophy favored by OEMs in commercial-grade mobile applications where reliability cannot be compromised.

Mechanics and fabricators building dual-battery systems, auxiliary lighting arrays, winch controls, or refrigeration units will find this converter indispensable for powering secondary 12-volt loads from a 24-volt primary system or isolated auxiliary battery bank. Installation requires secure mounting in an engine bay or equipment cabinet with proper ventilation; the compact 6 × 4 × 9-inch footprint fits most mounting locations. The 30-amp output capability ensures compatibility with high-draw accessories including LED light bars, compressors, and inverter supplies, making it a reliable choice for serious vehicle builds where power isolation and efficiency are non-negotiable.
