Samlex 100W Fully Isolated DC-DC Converter - 4A - 30-60V Input - 24V Output

The Samlex 100W Fully Isolated DC-DC Converter is purpose-built for mobile power systems where clean, regulated voltage conversion is non-negotiable—whether you're running auxiliary electronics in a custom 4x4, powering onboard diagnostic systems in a build truck, or maintaining stable 24V output for auxiliary lighting and communications gear. This isolated converter bridges the gap between high-voltage primary systems (30-60V input range) and sensitive 24V loads, eliminating ground-loop noise and protecting equipment from voltage transients common in vehicles with aftermarket electrical modifications. For mechanics and builders managing complex wiring harnesses, this unit is essential infrastructure.

Galvanic isolation is the engineering feature that sets this converter apart: input and output circuits are electrically isolated from one another, preventing the ground-loop hum and RF interference that plague undersized or poorly filtered DC supplies in noisy engine bays. The IDC-100C-24 model delivers a continuous 4A at 24V output (100W capacity), making it suitable for moderate auxiliary loads—auxiliary fuel pumps, underbody lighting systems, winch solenoids, or integrated telematics modules. High efficiency design minimizes heat generation and wasted power, a critical advantage in tight installation spaces where thermal management is already challenging. The 30-60V input range accommodates both 24V nominal systems and higher-voltage battery banks without requiring external regulators.

This converter is ideal for serious vehicle builders integrating multiple power domains—dual-battery setups, auxiliary power distribution modules, or integrated electronics suites where isolation prevents cascading failures and protects sensitive microcontroller circuits. Weighing just 1 lb, it's compact enough for under-seat mounting, interior panels, or fused distribution blocks without adding significant weight penalty. Installation is straightforward: connect primary voltage to input terminals, load to output, and ground the converter chassis to vehicle frame for optimal EMI suppression. Proper fusing on both input and output sides (sized per load specifications) is mandatory for safety and component longevity.
