Description
xVictron Orion-Tr 48/24-16A (380W) Isolated DC-DC Converter
The Victron Orion-Tr 48/24-16A is a galvanically isolated DC-DC converter that steps a 48V DC input down to a regulated 24V DC output at up to 16A (380W). It is designed for professional installations where electrical isolation between two DC systems is required, such as vehicle, marine, and off-grid applications.
Key Features
- Galvanic isolation between input and output, eliminating ground loop issues and protecting sensitive equipment.
- 48V input to 24V output conversion at a continuous 16A (380W) output rating.
- Wide input voltage range suitable for real-world 48V battery systems with varying state of charge.
- Output voltage is adjustable, allowing fine-tuning to match the requirements of the connected load or charging circuit.
- Compact and robust aluminium housing suitable for permanent installation in demanding environments.
- High conversion efficiency reduces heat generation and minimises energy losses in the system.
- Compatible with Victron's broader ecosystem, including use alongside MultiPlus, Quattro and other 48V system components.
Product Overview
The Orion-Tr range uses a transformer-based topology to provide true galvanic isolation between the input and output circuits. This is a practical requirement in many installations: it prevents unwanted current paths between two battery banks, protects against ground faults, and allows the output to float independently of the input reference. In a 48V system feeding a 24V auxiliary circuit, this isolation is often essential for safety and equipment compatibility.
At 380W continuous output, this converter handles meaningful loads: 24V lighting circuits, communication equipment, control systems, or secondary battery charging. The output voltage can be adjusted via an internal trimmer, which gives installers the flexibility to compensate for cable voltage drop or to set a precise float or absorption voltage when the unit is used to charge a secondary 24V battery bank.
The aluminium enclosure dissipates heat passively and is built for fixed installation. The unit does not include Bluetooth or remote on/off as standard, so installers should confirm whether remote switching or monitoring is required before specifying this model. For applications needing those features, Victron offers Smart and non-isolated variants within the Orion-Tr range.

Installation Notes
This unit must be installed by a competent electrician or qualified installer with experience in DC power systems. Correct fusing on both the input and output sides is required. Ensure the input wiring is rated for the full input current draw at 48V. The output voltage trimmer should only be adjusted with appropriate test equipment in place. For marine installations, follow the relevant wiring standards for the vessel type. Do not install in enclosed spaces without adequate ventilation for passive heat dissipation.
