DC/DC converters: precisely adapt your onboard voltages

Modern marine electronics demand rigorous voltage management. DC/DC converters are essential for adapting the voltages between the various components of your onboard electrical system. At Skysat, drawing on our experience in offshore racing, we offer a selection of robust and reliable converters designed to meet the demands of the marine environment.

Why use a DC/DC converter?

A DC/DC converter transforms one DC voltage into another DC voltage, while galvanically isolating the circuits. This is crucial to prevent ground loops and interference, and to ensure the safety of your equipment. A poor choice can lead to malfunctions or even irreversible damage.

• Victron Energy Orion-Tr Smart Isolated: Isolated inverters configurable via Bluetooth, ideal for charging auxiliary batteries or powering sensitive equipment. They offer high efficiency and protection against short circuits and overheating.
• Mastervolt DC-DC Power Supplier: Designed to provide a stable and clean voltage, even with input voltage fluctuations. Particularly suitable for embedded audio, video, and computer systems.
• Sterling Power Pro Batt Ultra: Bidirectional converters that allow charging one battery from another, with intelligent charge management to optimize battery life. Useful for systems with multiple battery banks.
• Mean Well Stabilized Power Supplies: Economical and reliable solutions for a wide range of applications, offering galvanic isolation and surge protection.

Criteria for selecting a DC/DC converter

Choosing the right DC/DC converter involves considering several key factors: the required input and output voltage, the power output, galvanic isolation, efficiency, and built-in protection features. Don't overlook the importance of cooling, especially for high-power converters.

• Input and output voltage: Ensure compatibility with the voltages of your batteries and equipment. For example, converting 24V to 12V to power an NMEA 2000 chartplotter.
• Rated power: Calculate the total power required to supply all devices connected to the inverter. Include a safety margin to prevent overloading.
• Galvanic isolation: Essential to prevent ground loops and electromagnetic compatibility issues. Check the isolation voltage specified by the manufacturer.
• Efficiency: High efficiency means less energy loss in the form of heat and better battery life.

Integration into your electrical network

Integrating a DC/DC converter requires careful attention to wiring and overcurrent protection. Use appropriately sized cables and suitable fuses to ensure the safety and reliability of your installation. A clear electrical diagram is essential.

• Cabling: Use high-quality marine cables that are corrosion and vibration resistant. Comply with applicable standards for cable sizing.
• Protection: Install appropriate fuses or circuit breakers to protect the converter and connected equipment from short circuits and overloads.
• Grounding: Ensure proper grounding of all equipment to avoid electromagnetic compatibility problems.
• Cooling: For high-power converters, provide adequate ventilation to prevent overheating.
