Description
xOrion-Tr 24/48-6A (280W) Isolated DC-DC Converter
The Victron Orion-Tr 24/48-6A is a galvanically isolated DC-DC converter that steps up a 24V DC input to a 48V DC output at up to 6A continuous current, delivering 280W of power. It is designed for professional installations where electrical isolation between input and output circuits is required, such as mixed-voltage vehicle systems, marine applications, and off-grid energy setups.
Key Features
- Galvanic isolation between input and output, eliminating ground loop issues and protecting sensitive equipment on either circuit.
- 24V input to 48V output conversion at 6A continuous, providing 280W of regulated DC power.
- Wide input voltage range typical of the Orion-Tr series, accommodating real-world battery voltage fluctuations without shutting down.
- Compact, enclosed metal housing suitable for fixed installation in vehicles, vessels and off-grid enclosures.
- Compatible with Victron's broader ecosystem, making it straightforward to integrate alongside Victron inverters, chargers and battery monitors.
- No cooling fan required: the unit is convection-cooled, reducing noise and mechanical failure risk.
Product Overview
The Orion-Tr isolated series differs from non-isolated DC-DC converters in one important respect: the input and output share no common electrical reference. This matters in dual-battery vehicle installations, marine systems with mixed grounding schemes, and any application where connecting two DC buses directly would create a fault path or ground loop. The isolation transformer inside the unit breaks that connection while still transferring power efficiently.
At 280W, this converter is suited to powering 48V loads or charging a 48V battery bank from a 24V source. Typical scenarios include supplementing a 48V lithium battery system from a 24V alternator or house bank, or running 48V DC equipment in a vehicle or vessel that operates a 24V primary system. The 6A output current is continuous, not peak, so the rating reflects sustained real-world use rather than a momentary figure.
The Orion-Tr range is a fixed-output converter, not a programmable charger. It is not a replacement for a dedicated battery-to-battery charger where charge profile management is needed. For straightforward voltage conversion with isolation, it is a well-specified, field-proven unit.

Applications
- Stepping up a 24V vehicle or vessel house bank to power 48V DC equipment or subsystems.
- Charging a 48V lithium or lead-acid battery bank from a 24V DC source where isolation is required.
- Off-grid and mobile installations where two DC voltage domains must remain electrically isolated.
- Marine systems with mixed grounding arrangements where a direct connection between buses would create corrosion or fault risks.
- Telecom and industrial enclosures requiring a regulated, isolated 48V supply from a 24V battery system.
What Is Included
- 1x Victron Orion-Tr 24/48-6A (280W) Isolated DC-DC Converter
Installation Notes
This unit should be installed by a qualified electrician or marine/vehicle electrical engineer familiar with DC power systems. Ensure input and output wiring is correctly rated for the current involved and that appropriate fusing is fitted on both the input and output sides. The galvanic isolation makes this converter suitable for installations where the two DC buses must not share a common ground, but correct installation practice is still essential to maintain that isolation. Do not exceed the rated input voltage range. Mount the unit in a ventilated location to allow convection cooling to function correctly.
