Description
Victron Orion-Tr 48/12 20A DC-DC Converter | Boat Supply Store
This isolated DC-DC converter effectively transforms 48V DC input to a stable 12V DC output, essential for powering sensitive 12V marine electronics from a higher voltage system. It delivers a continuous 20A output, translating to 240W of reliable power, with an IP43 ingress protection rating ensuring resilience against dust and water ingress when terminals are oriented downwards. Ideal for larger vessels or vessels with 48V house battery banks requiring 12V operation for navigation, communication, or entertainment systems.
Key Features
- Isolated DC-DC conversion prevents ground loops and protects sensitive 12V electronics.
- Remote on/off terminal allows for convenient system integration and power management.
- Short-circuit proof design ensures operator and equipment safety during fault conditions.
- Paralleling capability allows for scalable output by connecting multiple units for increased current capacity.
- High temperature protection automatically shuts down the unit to prevent damage from overheating.
- IP43 protection offers defense against dust and water spray when installed correctly.
- Screw terminals facilitate secure and straightforward electrical connections.
- Adjustable output voltage (not for battery charging) provides flexibility for specific voltage requirements.

Common Concerns Answered
Is this converter suitable for charging my 12V battery bank?
The Victron Orion-Tr 48/12 20A is specifically designed for power conversion and is not intended for direct battery charging. For battery charging applications from a 48V source, a Victron 'Smart' model or a dedicated battery-to-battery charger is required.
What if I need more output power than 240W?
The Orion-Tr series features paralleling capability, allowing you to connect multiple units together to achieve a higher total output current and power to meet your specific system demands.
Are there more advanced features available?
While this model provides essential isolated DC-DC conversion with robust protection, higher-end 'Smart' models from Victron Energy offer additional diagnostic features and advanced connectivity options for more complex system monitoring and control.
Frequently Asked Questions
Can the Victron Orion-Tr 48/12 20A be used for battery charging?
No, this specific model is not designed for battery charging. It functions as a power converter, providing a stable 12V DC output from a 48V DC input. For battery charging, consider a Victron 'Smart' version or a dedicated battery charger.
How can the remote on/off function be utilized?
The remote on/off terminal allows you to control the converter's operation using a separate switch or by connecting it to your boat's ignition system. This provides convenient power management, enabling you to switch the converter off when not needed to conserve energy.
What is the maximum output current for this DC-DC converter?
The Victron Orion-Tr 48/12 20A provides a maximum continuous output current of 20 Amperes (A), with a total output power of 240 Watts (W).
Can multiple Victron Orion-Tr 48/12 20A units be connected in parallel?
Yes, the Victron Orion-Tr 48/12 20A features paralleling capability, allowing you to connect multiple units in parallel to increase the total output current to meet higher power demands.
What is the IP rating of the Victron Orion-Tr 48/12 20A?
The Victron Orion-Tr 48/12 20A has an IP43 protection rating, indicating it is protected against solid objects greater than 1mm (dust ingress) and protected against water spray at an angle up to 60° from the vertical, provided the screw terminals are oriented downwards.
