Samlex 100W Fully Isolated DC-DC Converter - 8A - 30-60V Input - 12.5V Output

The Samlex 100W Fully Isolated DC-DC Converter is purpose-built for anglers and boaters running dual-voltage systems where galvanic isolation between input and output circuits is non-negotiable. Whether you're powering 12V navigation electronics, fish finders, or cabin systems from a high-voltage auxiliary battery bank (30–60V range), this converter provides the electrical separation that prevents ground loops and protects sensitive marine electronics from voltage spikes and noise. It's the difference between clean power and a degraded sonar display or unreliable GPS signal when you need it most.

The IDC-100C-12 delivers a robust 100 watts at 12.5V output with an 8-amp continuous current rating, engineered with full isolation topology to eliminate common-mode voltage transients that plague marine electrical systems. High-efficiency switching design minimizes heat generation in tight engine compartments, and the compact 4 x 2 x 6-inch form factor fits easily behind dashboards or under consoles. Wide 30–60V input acceptance accommodates older 24V systems, newer 48V lithium setups, and everything between—making this converter a future-proof choice for vessels undergoing electrical upgrades.

This converter is ideal for center console boats, cruising yachts, and commercial fishing vessels where multiple voltage sources must coexist safely. Anglers running 24V or 48V trolling motor systems who also need reliable 12V for autopilot, sounder, and VHF radio will find this unit indispensable for isolation-critical installations. Marine-grade construction and Samlex America's reputation for reliability make it suitable for both freshwater and saltwater environments; installation requires straightforward DC input/output termination with proper fusing on the input side to meet marine electrical code.
