Description
xVictron Orion-Tr 24/24-5A 120W Isolated DC-DC Converter
The Victron Orion-Tr 24/24-5A is a galvanically isolated DC-DC converter rated at 120W, designed to step or maintain a 24V input to a regulated 24V output. It is suited to professional vehicle, marine, and off-grid installations where electrical isolation between two 24V systems is required to prevent ground loops, protect sensitive electronics, or charge a secondary battery bank independently.
Key Features
- Galvanic isolation between input and output, eliminating ground loop interference between separate DC systems.
- 24V input to 24V output at up to 5A continuous, delivering 120W of isolated DC power.
- Wide input voltage range typical of the Orion-Tr series, accommodating voltage fluctuations common in vehicle and battery systems.
- Compact, enclosed housing suitable for installation in confined spaces such as vehicle cabinets, battery compartments, and marine panels.
- Fixed output voltage suitable for maintaining or charging a secondary 24V battery or powering 24V DC loads in isolation.
- Victron Orion-Tr series build quality, consistent with use in demanding mobile and off-grid environments.
Product Overview
Galvanic isolation is the key distinction between the Orion-Tr range and a standard DC-DC converter. By electrically separating the input and output circuits, the converter prevents current from flowing between two battery systems through the chassis or common ground. This matters in dual-battery vehicle installations, boat electrical systems, and any application where two DC networks must remain independent for safety or equipment protection reasons.
The 24/24-5A variant is specifically useful where the source and load voltages are both nominally 24V but the systems must remain isolated. Typical scenarios include charging a service battery from a starter battery on a 24V truck or coach, or powering sensitive 24V instrumentation from a main 24V bank without risking interference. At 120W continuous output, it handles moderate loads and battery charging duties without requiring a larger, heavier unit.
The Orion-Tr series is a well-established product line within the Victron Energy portfolio, and the isolated variants are widely used by professional installers in the marine, automotive, and off-grid sectors. The unit is supplied in retail packaging, making it straightforward to handle as a stocked component for trade or project use.

Installation Notes
Installation should be carried out by a qualified electrician or experienced marine/vehicle electrical engineer. Ensure input and output wiring is correctly rated for the current draw and that appropriate fusing is fitted on both the input and output circuits. Verify that the input voltage range of the unit is compatible with your source battery system under all operating conditions, including engine-on charging voltages. For marine installations, follow applicable wiring standards for the vessel type.
