The Victron Orion-Tr 12/12-30A is a galvanically isolated DC-DC converter rated at 360W. It steps 12V input to 12V output while keeping the two circuits fully isolated, which matters in vehicle, marine and off-grid installations that run two separate battery banks.

Victron Orion-Tr 12/12-30A isolated DC-DC converter features

• Galvanic isolation, input and output share no electrical connection, avoiding ground loops and protecting output-side electronics.
• Output current, up to 30A continuous, 360W total output.
• Adjustable output voltage, can be tuned to suit flooded lead-acid, AGM, gel or lithium iron phosphate batteries.
• Fanless cooling, convection cooled through the aluminium housing, with no moving parts.
• Weight, 1.8kg, compact enough for a vehicle cabinet or a marine bilge space.
• Fully encapsulated, built to cope with vibration and moisture in mobile and marine settings.

Specifications

Applications

Charging an auxiliary or leisure battery from a vehicle starter battery, with full isolation between the two banks. Marine dual-battery systems where galvanic isolation prevents corrosion and ground loop interference. Motorhome and campervan builds needing isolated power between chassis and habitation circuits. Off-grid mobile setups charging a secondary lithium battery from a lead-acid primary source, and truck or commercial vehicle auxiliary systems where electronics protection matters.

Installation notes

Fit this with a qualified auto-electrician or marine electrician. Fuse both the input and output sides to match the cables used, mount the unit so convection airflow around the housing is not blocked, and follow relevant marine wiring standards on boats. Set the adjustable output voltage before the output battery is connected.
