The Victron Orion-Tr 12/24-10A is a galvanically isolated DC-DC converter that steps a 12V supply up to a regulated 24V output at up to 10A, delivering 240W. It suits professional installations where electrical isolation between input and output circuits matters, including vehicle, marine and off-grid systems.

Key features

• Galvanic isolation, no shared ground between input and output, reducing ground loop issues and protecting equipment from voltage spikes on the source circuit.
• Conversion, 12V input to 24V output at up to 10A continuous, giving 240W of regulated DC power.
• Wide input range, tolerates real-world battery voltage swings, including partial charge and engine-running conditions.
• Compact housing, enclosed unit weighing 1.3kg, suited to confined installation spaces.
• Adjustable output voltage, can be tuned to match the connected load or battery bank rather than relying on a fixed default.

Product overview

Dual-voltage systems often need to power 24V equipment or charge a 24V battery from a 12V source without an electrical connection between the two circuits. Galvanic isolation removes that shared ground, which matters on boats and vehicles where chassis grounds can bring noise, corrosion currents or fault paths into the system.

At 240W continuous output, this converter charges auxiliary 24V battery banks, runs 24V DC loads, or supplies 24V equipment from a 12V vehicle or solar system. The adjustable output lets an installer set the correct charge or supply voltage rather than accepting a factory default.

A high-frequency switching design keeps the unit compact. The enclosed housing protects internal components from dust and moisture, suiting marine, motorhome and off-grid cabinet environments.

Applications

• Charging a 24V auxiliary battery bank from a 12V vehicle or boat electrical system.
• Powering 24V DC loads from a 12V solar or battery system where isolation is required.
• Dual-voltage marine installations needing galvanic isolation to prevent corrosion currents between circuits.
• Motorhome and campervan conversions requiring a regulated 24V supply from a 12V leisure battery.
• Off-grid cabinet installations supplying 24V equipment from a 12V battery bank.

Installation notes

Fit this unit with a qualified electrician or experienced systems integrator familiar with DC power systems. Wiring on both input and output must be correctly rated for the current involved, with fusing fitted on each side. Marine installations should follow NMEA or flag-state wiring standards. Galvanic isolation does not replace correct system earthing and bonding practice.
