Description
xVictron Orion-Tr 12/12-30A (360W) Isolated DC-DC Converter — ORI121240110
The Victron Orion-Tr 12/12-30A is a galvanically isolated DC-DC converter rated at 360W, designed to step between 12V sources and 12V loads while maintaining full electrical isolation between input and output. It is suited to professional vehicle, marine and off-grid installations where two battery banks must be kept electrically separate.
Key Features
- Galvanic isolation between input and output eliminates ground loop issues and protects sensitive electronics on the output side.
- 12V input to 12V output at up to 30A continuous output current, delivering 360W of converted power.
- Wide input voltage range accommodates real-world battery voltage fluctuations during charging and discharge cycles.
- Compact and lightweight at 1.8 kg, making it practical for installation in confined spaces such as vehicle cabinets or marine bilge areas.
- Fully encapsulated design provides protection against vibration and moisture ingress, appropriate for mobile and marine environments.
- Output voltage is adjustable, allowing fine-tuning to suit specific battery chemistries or load requirements.
- Silent operation with no cooling fan, relying on convection cooling through the aluminium housing.
Product Overview
The Orion-Tr isolated range differs from non-isolated DC-DC converters in one critical respect: the input and output circuits share no electrical connection. This matters in dual-battery vehicle systems, where connecting a starter battery bank directly to a leisure or auxiliary bank without isolation can cause ground loops, interfere with vehicle electronics, or create fault paths that bypass fusing. The galvanic isolation in this unit removes those risks entirely.
At 30A output and 360W, this converter is capable of charging a secondary lithium or AGM battery bank from a vehicle or vessel's primary 12V system at a meaningful rate. The adjustable output voltage means it can be configured to suit flooded lead-acid, AGM, gel or lithium iron phosphate batteries without requiring an external charge controller on the output side. The unit operates without a fan, which keeps installation straightforward and eliminates a potential failure point in harsh environments.
The Orion-Tr 12/12-30A is part of Victron's broader Orion-Tr isolated converter range, which shares a consistent form factor and wiring approach across different voltage and power ratings. This makes it a practical choice for installers who work across multiple vehicle or marine platforms.

- Marine dual-battery systems where galvanic isolation is required to prevent corrosion and ground loop interference.
- Motorhome and campervan builds requiring isolated DC power distribution between chassis and habitation circuits.
- Off-grid mobile installations where a secondary lithium battery must be charged from a lead-acid primary source without direct connection.
- Truck and commercial vehicle auxiliary power systems where electronics protection is a priority.

Installation Notes
Installation should be carried out by a qualified auto-electrician or marine electrician familiar with DC power systems. Ensure correct fusing on both the input and output sides in accordance with the cable ratings used. The unit must be mounted to allow adequate convection airflow around the housing. For marine installations, observe NMEA or relevant marine wiring standards. The adjustable output voltage should be set before connecting the output battery to avoid overcharging. Do not install in fully sealed enclosures without accounting for heat dissipation.
