Samlex 100W Fully Isolated DC-DC Converter - 4A - 9-18V Input - 24V Output

The Samlex 100W Fully Isolated DC-DC Converter is engineered for professionals and enthusiasts who demand reliable power distribution in mobile and stationary electrical systems. Whether you're upgrading your vehicle's auxiliary power architecture, powering dual-battery setups, or integrating auxiliary equipment into trucks and RVs, this isolated converter bridges input voltages of 9–18V to a stable 24V output with 4A capacity. Galvanic isolation between input and output eliminates ground loop noise and protects sensitive electronics from voltage spikes common in automotive environments.

The IDC-100A-24 operates at high efficiency and is built to withstand the thermal and electrical stress of extended mobile installations. Its compact footprint (4 x 2 x 6 inches) makes it ideal for under-dash, battery box, or engine compartment mounting where space is constrained. Fully isolated topology means the converter can operate independently from the vehicle's main electrical ground, reducing EMI interference with audio systems, navigation, and communications gear—a critical advantage in heavily modified rigs with aftermarket amplifiers or complex accessory networks. The 100W power handling supports multiple loads simultaneously without voltage sag.

This converter suits dual-battery platforms, auxiliary lighting systems, onboard compressors, winch controls, and 24V accessory circuits in 12V vehicle chassis. Installation requires clean 9–18V source input (typically a primary or secondary battery) and secure mounting with adequate airflow to ensure thermal dissipation during continuous operation. The lightweight 1.3 lb design simplifies installation without compromising durability, and its isolated output prevents feedback that would otherwise degrade alternator charging or parasitic drain management on sensitive electrical systems.
