Description
xVictron Orion-Tr 24/48-2.5A (120W) Isolated DC-DC Converter
The Victron Orion-Tr 24/48-2.5A is a galvanically isolated DC-DC converter that steps up a 24V DC input to a 48V DC output at 2.5A continuous, delivering up to 120W. It is designed for professional use in mobile, marine, off-grid and industrial applications where two separate DC systems must be connected without a shared ground reference.
Key Features
- Galvanic isolation between input and output, allowing connection of two electrically independent DC systems without ground loops or interference.
- 24V input to 48V output conversion at 2.5A continuous current, rated at 120W.
- Wide input voltage range typical of the Orion-Tr series, accommodating real-world battery voltage fluctuations on 24V systems.
- Compact and lightweight at 0.5kg, suitable for installation in space-constrained enclosures, vehicles and vessels.
- Designed for continuous duty cycle operation, making it suitable for permanent installations rather than occasional use.
- Fixed output voltage, providing a stable 48V supply to connected loads or charging circuits.
Product Overview
The Orion-Tr range from Victron Energy uses a fully isolated transformer-based topology. Galvanic isolation means the input and output circuits share no electrical connection, which is essential when integrating two battery banks with separate grounds, or when connecting sensitive electronics that must be protected from ground-referenced noise. In marine and vehicle applications, this also prevents corrosion caused by stray currents.
At 120W, this converter is suited to powering 48V loads or topping up a 48V battery from a 24V source in systems where a full-size charger is not practical. Typical scenarios include powering 48V communication equipment, lighting circuits or auxiliary electronics from a 24V house bank. The fixed output voltage means no adjustment is required, simplifying installation in straightforward step-up applications.
The Orion-Tr series is a well-established product line within the Victron ecosystem and is compatible with standard DC wiring practices. This unit does not include Bluetooth or VE.Direct connectivity; it operates as a standalone converter without remote monitoring or programmable output adjustment.

Installation Notes
This converter should be installed by a qualified electrician or competent marine/vehicle electrician familiar with DC wiring practices. Ensure correct fusing on both the input and output circuits in accordance with the wire gauge used. The unit is designed for fixed installation; secure it to a suitable surface with adequate ventilation. Verify that the 24V source voltage remains within the converter's specified input range under all load conditions before commissioning.
