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 mobile, marine and off-grid applications where two battery banks must be kept electrically separate, or where a 24V load needs to be powered from a 12V source.
Key Features
- Galvanic isolation between input and output, preventing ground loops and protecting sensitive electronics on separate battery banks.
- 12V nominal input to 24V regulated output at 5A continuous (120W).
- Wide input voltage range suitable for real-world 12V battery systems, including during charging and under partial load.
- Compact, fully enclosed aluminium housing rated for demanding environments.
- High conversion efficiency, minimising heat generation and reducing drain on the source battery.
- Fixed output voltage with no need for external adjustment in standard installations.
- Compatible with lead-acid and lithium battery chemistries on both input and output sides.
Product Overview
Galvanic isolation is the key distinction of the Orion-Tr range over non-isolated DC-DC converters. The transformer-based isolation barrier means the input and output circuits share no electrical connection, which matters in vehicles, boats and dual-battery systems where a common ground between two banks would cause charging interference, corrosion currents or damage to electronics. This converter allows a 24V device or battery to be powered or charged from a 12V source without any shared ground path.
The 5A output at 24V gives 120W of usable power, which is sufficient for charging a secondary 24V battery bank, running 24V control systems, or supplying 24V DC loads from a 12V vehicle or solar system. The Orion-Tr range is built around a robust switching topology that maintains regulated output across a realistic range of input voltages, so performance does not degrade as the source battery discharges under load.
Victron's Orion-Tr converters are widely used in professional marine and vehicle installations. The isolated design also makes them suitable for use in systems where the installer needs to meet specific electrical separation requirements, such as on vessels complying with marine wiring standards.

Installation Notes
Installation should be carried out by a qualified electrician or experienced system integrator familiar with DC wiring practices. Ensure input and output wiring is correctly rated for the current involved and that appropriate fusing is fitted on both the input and output sides. In marine applications, follow the relevant wiring standards for your vessel class. The galvanic isolation eliminates shared ground issues, but correct polarity and secure terminations remain essential. This product is not grid-connected and does not require G98 or G99 compliance.
