Description
xVictron Orion-Tr 24/12-30A (360W) Isolated DC-DC Converter — ORI241240110
The Victron Orion-Tr 24/12-30A is a galvanically isolated DC-DC converter that steps a 24V DC input down to a regulated 12V DC output at up to 30A (360W). It is designed for professional use in vehicles, marine installations, off-grid systems and anywhere a stable, isolated 12V supply is needed from a 24V source.
Key Features
- Galvanic isolation between input and output, eliminating ground loop issues and protecting sensitive electronics from noise on the supply rail.
- 24V input to 12V output conversion at 30A continuous, delivering up to 360W of regulated DC power.
- Wide input voltage range accommodates real-world battery voltage fluctuations typical in 24V systems.
- Output voltage is adjustable, allowing fine-tuning to suit specific loads or battery chemistries.
- Compact, fully enclosed aluminium housing suitable for fixed installation in confined spaces.
- Protected against short circuit, over-temperature and reverse polarity on the input.
- Weight of 1.8 kg makes it practical for mobile and marine installations where weight is a consideration.
Product Overview
The Orion-Tr range uses a transformer-based isolated topology, which means the input and output circuits share no common electrical connection. This is particularly important in dual-battery vehicle systems, boats and motorhomes where chassis grounds from different circuits can cause interference or corrosion through stray currents. The isolation also protects downstream 12V equipment from transients present on the 24V bus.
At 360W continuous output, this unit is well suited to powering 12V accessory circuits, charging a secondary 12V battery from a 24V alternator or house bank, or supplying 12V loads in a mixed-voltage system. The adjustable output voltage means it can be set to deliver a slightly elevated voltage for float charging a 12V lead-acid battery, or dialled back for powering fixed 12V loads directly.
Victron's Orion-Tr converters are widely used by professional installers in commercial vehicles, ambulances, narrowboats, yachts and off-grid cabins. The build quality and protection features make them a practical choice where reliability matters and replacement is inconvenient.

Installation Notes
Installation should be carried out by a qualified electrician or experienced DC systems installer. Ensure input and output wiring is correctly rated for the current involved and that appropriate fusing is fitted on both the input and output circuits. The unit must be mounted in a ventilated location and kept clear of flammable materials. For marine installations, follow NMEA and RCD Directive wiring standards. Verify input voltage compatibility before connecting to any battery system.
