Victron Orion-Tr 48/12-9A Isolated DC-DC Converter

📝 Victron Orion-Tr 48/12-9A (110W) Isolated DC-DC Converter (Not a charger)

The Victron Orion-Tr 48/12-9A Isolated DC-DC Converter delivers efficient, reliable power conversion from 48v to 12v, ideal for maintaining stable voltage across a wide range of DC systems. With galvanic isolation for enhanced protection and adjustable voltage control, it’s the perfect solution for powering sensitive equipment in marine, RV, caravan, industrial, and off-grid setups.

⭐ Essential Benefits

• Efficient isolated power conversion – delivers over 95% efficiency for minimal heat and energy loss.
• Electrical isolation – prevents interference between systems and protects sensitive electronics.
• Remote on/off capability – integrates easily with ignition or control switches for flexible operation.
• Adjustable output voltage – fine-tune the voltage for customised power delivery or light charging.
• Parallel-ready – connect multiple units to scale power output for larger systems.
• Comprehensive protection – includes short-circuit, overload, and over-temperature safeguards.
• IP43 rating – dust and water-resistant when mounted with terminals facing downwards.

⚙️ Functionality

The Orion-Tr 48/12-9A provides stable DC voltage reduction using galvanic isolation to safeguard connected devices from electrical noise or grounding conflicts.
