Samlex 360W Fully Isolated DC-DC Converter - 30A - 30-60V Input - 12.5V Output

The Samlex 360W Fully Isolated DC-DC Converter is purpose-built for serious boaters and anglers who demand clean, reliable power conversion in multi-battery systems. Whether you're running a modern electronics suite on a 48V lithium bank, trolling motor setup, or hybrid power configuration, this converter steps down high-voltage input to a stable 12.5V output without ground loops—a critical feature when sensitive navigation, fish-finding, and communication gear share the same electrical backbone.

Full galvanic isolation is the engineering that sets this unit apart. The IDC-360C-12 accepts input voltage between 30–60V DC and delivers a regulated 12.5V output at up to 30A continuous, yielding 360 watts of power capacity. Isolation prevents voltage transients and noise from the main battery bank from corrupting data signals on your VHF radio, GPS chartplotter, or sounder—issues that plague non-isolated converters in dual-voltage vessels. The compact 6×4×9-inch footprint and 3.3-pound weight make installation straightforward in engine rooms or battery compartments where space is at a premium.

This converter excels in boats transitioning to high-voltage propulsion or auxiliary power systems while retaining legacy 12V accessory loads. Anglers with advanced sonar arrays, autopilots, and trim-and-tilt systems benefit from the clean power delivery and noise immunity. Proper cooling via forced-air circulation ensures reliability during extended offshore runs or tournament days. Mount it near the input source, observe wire gauge requirements for the 30A input circuit, and ensure adequate ventilation around the unit for optimal longevity in the harsh marine environment.
