Victron Orion-Tr 48/12-9A (110W) Isolated DC-DC Converter
Step down high-voltage power safely and efficiently with the Victron Orion-Tr 48/12-9A Isolated DC-DC Converter. Designed to convert a 48V DC input down to a stable 12V DC output at up to 9 Amps (110W), this converter is ideal for powering 12V accessories, lighting, electronics, or appliances from a 48V battery bank or solar power setup.
Galvanic isolation ensures complete electrical separation between input and output circuits, protecting sensitive equipment from ground loops, electrical noise, and voltage spikes.
Key Features
- Galvanic Isolation: Completely separates the input and output electrical circuits, protecting downstream electronics from noise and power spikes.
- Remote On/Off Terminal: Eliminates the need for a heavy-duty, high-current switch on the input wiring. Control the converter using a simple low-power switch or connect it to an engine run/stop signal.
- Adjustable Output Voltage: Can be fine-tuned or used as a multi-stage battery charger to maintain a 12V starter or auxiliary battery from a 48V main system.
- IP43 Ingress Protection: Built for harsh environments—protected against spray and debris when installed with screw terminals pointing downward.
- Short-Circuit & High-Temperature Protected: Features automatic output current reduction during high ambient temperatures and full short-circuit protection for reliable operation.
- Easy Screw-Terminal Installation: Standard screw terminals mean quick installation without requiring specialized crimping or connector tools.
