Description
xVictron Orion-Tr 24/12-9A (110W) Isolated DC-DC Converter
The Victron Orion-Tr 24/12-9A is a galvanically isolated DC-DC converter that steps a 24V DC input down to a 12V DC output at up to 9A continuous current. It is designed for professional use in vehicles, marine installations, and off-grid systems where two battery banks must remain electrically isolated from one another.
Key Features
- Galvanic isolation between input and output, preventing ground loops and protecting sensitive electronics on the 12V side.
- 24V input to 12V output conversion at 9A continuous, delivering up to 110W of usable power.
- Wide input voltage range accommodates real-world 24V battery systems, including variation during charging and discharge cycles.
- Compact and lightweight at 0.5kg, suitable for installation in confined spaces such as panel boards, lockers and engine bays.
- Fixed output voltage with stable regulation, suitable for powering 12V loads directly from a 24V house or starter battery bank.
- Fully encapsulated design provides protection against vibration and moisture ingress, appropriate for mobile and marine environments.
Product Overview
The Orion-Tr range uses a transformer-based isolated topology, which means the input and output circuits share no common electrical path. This matters in dual-battery installations where a 24V service bank needs to supply 12V accessories without creating a ground fault path between the two systems. It also eliminates the risk of a fault on the 12V side propagating back into the 24V bank.
At 110W output, this unit is well suited to powering 12V loads such as lighting circuits, control electronics, communication equipment, or charging smaller 12V batteries from a larger 24V bank. The regulated output means connected equipment receives a stable voltage regardless of normal fluctuations on the 24V input side. The Orion-Tr is not a battery-to-battery charger: it is a power converter for continuous load supply. For charging a 12V battery from a 24V source, the Orion-Tr Smart range with charge profiles is the appropriate product.

Installation Notes
Installation should be carried out by a qualified electrician or experienced system integrator familiar with DC power systems. Ensure correct fusing on both the input and output sides in accordance with the wire gauge used. The unit must be mounted in a ventilated location away from direct water ingress. For marine installations, follow NMEA or flag-state wiring standards as applicable. This converter is not suitable for use with AC supplies under any circumstances.
