Apollo - MarinePro Series DC-DC Converter – 15-58V IN to 12V 3A OUT, 36W Waterproof Power Module

Rugged Power in Compact Form: The Marine-Grade DC-DC Converter You Can Trust

This DC-DC Converter is designed with the demanding marine environment in mind. Whether you’re navigating open waters or anchored at dock, it ensures a constant, reliable 12V output even when your input voltage varies wildly between 15V and 58V. Its intelligent voltage regulation makes it ideal for boats, yachts, and marine electronics that require stable performance under dynamic conditions.

Stable 12V Output for Sensitive Electronics

Delivering a consistent 12V at up to 3A (36W max), this converter protects your devices from voltage spikes or drops. It's perfect for powering radios, GPS systems, LED lights, or communication equipment onboard. Engineered to eliminate the risk of over-voltage and under-voltage, it guarantees clean, uninterrupted energy to sensitive marine electronics.

Wide Voltage Input Range from 15V to 58V

Its ultra-flexible input range makes this converter highly compatible with a wide variety of battery systems and power sources, including solar panel setups, alternators, and multi-voltage DC grids often found in marine applications. No matter your input source, this unit will smartly adapt to ensure the delivery of a precise 12V output.

Built for Harsh Marine Environments

Constructed to withstand the unpredictable conditions of marine life, this converter features a durable, corrosion-resistant casing. Compact in size—measuring just 74 x 74 x 32mm—it fits snugly into tight installation spaces while offering powerful performance. Its sealed design offers reliable protection against moisture, vibration, and salt air.

Intelligent Thermal and Overload Protection

Worry-free operation is ensured through built-in protection systems that safeguard against overheating, overloads, and short circuits. The converter self-regulates under strain, reducing the chance of failure and extending the life of your onboard electronics and the converter itself.
