Description
xVictron Orion-Tr 12/12-9A (110W) Isolated DC-DC Converter
The Victron Orion-Tr 12/12-9A is a galvanically isolated DC-DC converter designed to charge a secondary 12V battery from a 12V source without any electrical connection between the two circuits. It is suited to vehicles, boats, caravans and off-grid installations where two separate battery banks must be kept electrically isolated from one another.
Key Features
- Galvanic isolation between input and output eliminates ground loop issues and protects sensitive electronics on the secondary circuit.
- 110W continuous output power at 9A on a 12V output from a 12V input source.
- Wide input voltage range accommodates fluctuating alternator or solar charge voltages without shutting down.
- Compact and lightweight at 0.5 kg, suitable for installation in confined spaces such as vehicle cabinets or marine bilge areas.
- Fixed output voltage provides a stable charge source for lead-acid and other 12V battery chemistries.
- Designed for continuous duty, making it suitable for permanent installation rather than occasional use.
Product Overview
The Orion-Tr range uses a transformer-based topology to provide true galvanic isolation between input and output. This matters in dual-battery systems where the two banks serve different purposes, for example a starter battery and a leisure battery in a motorhome or a bow thruster bank and a house bank on a boat. Without isolation, a fault on one circuit can propagate to the other. The Orion-Tr prevents this entirely.
At 110W and 9A output, this unit is sized for moderate secondary battery charging duties. It will maintain a leisure or auxiliary battery in good condition when the vehicle or vessel is running, without drawing excessive current from the primary source. The fixed output voltage means no programming is required, which simplifies installation compared to adjustable or programmable variants.
Victron's Orion-Tr converters are built for permanent, continuous installation. The aluminium enclosure dissipates heat effectively without requiring forced cooling in most applications, and the unit carries no minimum load requirement, so it can be left connected without risk of damage when the secondary battery is fully charged.

Installation Notes
Installation should be carried out by a qualified electrician or experienced 12V systems installer. Ensure correct cable sizing and fusing on both the input and output sides in accordance with the current rating of the unit. The input and output circuits must not share a common ground if galvanic isolation is to be maintained. For marine installations, follow the relevant BMEA or IEC wiring standards. This unit is not intended for grid-connected or mains-voltage applications.
