Description
xVictron Orion-Tr 48/12-30A (360W) Isolated DC-DC Converter — ORI481240110
The Victron Orion-Tr 48/12-30A is a galvanically isolated DC-DC converter that steps a 48V DC input down to a regulated 12V DC output at up to 30A (360W). It is designed for professional installations where electrical isolation between two DC systems is required, such as in vehicles, vessels, off-grid systems and industrial equipment.
Key Features
- Galvanic isolation between input and output, eliminating ground loop issues and protecting sensitive electronics.
- 48V input to 12V output conversion at 30A continuous current, delivering up to 360W of regulated DC power.
- Wide input voltage range typical of the Orion-Tr series, accommodating real-world battery voltage fluctuations on 48V systems.
- Compact, enclosed aluminium housing suitable for fixed installation in confined spaces.
- Output voltage is adjustable, allowing fine-tuning to suit specific load or charging requirements.
- Can be used in parallel with additional Orion-Tr units to increase output current capacity.
- Compatible with Victron system architectures including those using 48V lithium or lead-acid battery banks.
Product Overview
The Orion-Tr isolated series differs from standard DC-DC converters by providing full galvanic isolation between the input and output circuits. This matters in practice when connecting two battery systems that share a chassis ground, or when powering 12V loads from a 48V bank in a mixed-voltage installation. Without isolation, ground loops can cause noise, measurement errors or corrosion in sensitive systems. The Orion-Tr eliminates this risk entirely.
At 360W continuous output, this unit is well suited to powering 12V auxiliary loads, charging a secondary 12V battery from a 48V house bank, or supplying 12V control circuits in larger off-grid or marine installations. The adjustable output voltage means it can be set to deliver a precise charge voltage for a 12V lead-acid or lithium battery rather than a fixed supply voltage. Installation is straightforward with clearly labelled screw terminals and a compact footprint, though the unit weighs 1.8kg and should be mounted securely on a flat surface with adequate ventilation.
Multiple Orion-Tr units can be wired in parallel to scale output current beyond 30A where higher loads demand it. This makes the platform flexible for larger builds without requiring a different product entirely.

Installation Notes
This unit should be installed by a qualified electrician or experienced systems integrator familiar with DC power systems. Ensure input wiring is correctly fused at the source and that the mounting surface allows adequate airflow around the unit. The output voltage adjustment should be set before connecting loads. For installations forming part of a larger battery or solar system, verify compatibility with all connected equipment before commissioning.
