Description
xVictron Orion-Tr 12/24-5A (120W) Isolated DC-DC Converter
The Victron Orion-Tr 12/24-5A is a galvanically isolated DC-DC converter that steps a 12V input up to a regulated 24V output at 5A continuous, delivering up to 120W. It is designed for professional mobile, marine and off-grid installations where electrical isolation between two DC systems is required for safety or compatibility reasons.
Key Features
- Galvanic isolation between input and output, eliminating ground loop issues and protecting sensitive electronics in dual-battery or mixed-voltage systems.
- 12V nominal input to 24V regulated output at 5A continuous current, with a maximum output power of 120W.
- Wide input voltage range accommodates real-world battery conditions, including voltage sag under load.
- Compact and lightweight at 0.5kg, suitable for installation in confined spaces on vehicles, vessels and off-grid enclosures.
- Fixed output voltage with stable regulation, making it suitable for powering 24V loads directly from a 12V battery bank.
- Compatible with Victron's broader ecosystem of battery management and monitoring products.
Product Overview
The Orion-Tr range uses a transformer-based topology to provide true galvanic isolation between the input and output circuits. This matters in practice when connecting two independent battery systems, or when powering 24V equipment from a 12V source in a vehicle or vessel where a common ground could cause interference, corrosion or safety issues. The isolation barrier also protects downstream equipment from voltage spikes originating on the input side.
At 120W output, this unit is suited to powering moderate 24V loads such as communication equipment, control panels, instrumentation or secondary battery charging where the source bank operates at 12V. The regulated output voltage remains stable across the input range, which is important when battery voltage fluctuates during charge and discharge cycles.
The Orion-Tr 12/24-5A is a fixed-voltage converter. It does not include a remote on/off control or programmable output adjustment. For applications requiring those features, Victron offers other variants in the Orion-Tr Smart range. Installation is straightforward, but correct cable sizing and fusing on both the input and output sides is essential given the current levels involved.

Installation Notes
Installation should be carried out by a qualified electrician or experienced system integrator familiar with DC wiring practices. Both the input and output circuits must be correctly fused as close to the source as practicable. Ensure cable cross-sections are rated for the full input current, which will be higher than the output current due to the voltage step-up. For marine installations, follow NMEA or flag-state wiring standards as applicable. This unit is not intended for connection to AC mains circuits.
