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 vehicle electrical systems that demand stable, isolated power conversion in harsh mobile environments. Whether you're running auxiliary electronics in an overland build, powering communication systems in a service truck, or managing multi-voltage systems in a custom installation, this converter bridges the gap between a vehicle's alternator output and sensitive 12.5V loads.

Fully isolated topology eliminates ground loop noise and protects downstream electronics from alternator ripple and voltage spikes—critical when integrating modern aftermarket systems into older charging architectures or multi-source power configurations. Built by Samlex America, a recognized leader in mobile DC-DC technology, this unit accepts input from 9–18V sources and delivers a regulated 12.5V output at continuous 30A capacity (360W total). Isolation between input and output stages prevents transient voltage from engine cranking, alternator regulation changes, or high-current load dumps from reaching sensitive microprocessors, radios, or battery management systems.

The compact footprint—6 x 4 x 9 inches and 3.3 pounds—fits easily behind dashboards, under seats, or in engine bays, while industrial-grade components and thermal management ensure reliability in temperature extremes common to mobile installations. Mechanics and fabricators favor this converter for hybrid charging systems, auxiliary battery splits, and portable power tool circuits, making it an essential component for anyone looking to enhance their vehicle's electrical capabilities.
