Victron Orion-Tr 24/48-6A Isolated DC-DC Converter 280W | ORI244828110

The Victron Orion-Tr 24/48-6A is a galvanically isolated DC-DC converter that steps a 24V DC input up to a 48V DC output, delivering 6A continuous current and 280W of regulated power. It suits installations where electrical isolation between input and output circuits matters, including mixed-voltage vehicle systems, marine setups and off-grid energy systems.

Key features of this victron dc dc converter

• Galvanic isolation, transformer isolated, removing shared ground reference between input and output circuits.
• Voltage conversion, 24V DC input to 48V DC output.
• Output current, 6A continuous, delivering 280W.
• Cooling, convection cooled, no fan fitted.
• Housing, enclosed metal case for fixed installation in vehicles, vessels or off-grid enclosures.
• System integration, works alongside other Victron inverters, chargers and battery monitors.

Product overview

Isolated Orion-Tr converters differ from non-isolated types in one respect: input and output share no common electrical reference. That matters in dual-battery vehicles, marine systems with mixed grounding, or anywhere connecting two DC buses directly would create a fault path or ground loop. An isolation transformer inside the unit breaks that connection while still transferring power.

At 280W, this converter suits powering 48V loads or charging a 48V battery bank from a 24V source. Typical uses include topping up a 48V lithium bank from a 24V alternator or house bank, or running 48V DC equipment aboard a vehicle or vessel with a 24V primary system. The 6A rating is continuous, not peak, reflecting sustained use rather than a momentary figure.

This is a fixed-output converter, not a programmable charger, so it is not a substitute for a dedicated battery-to-battery charger where charge profile management is needed. For straightforward isolated voltage conversion it is a well-specified, field-proven unit.

Applications

• Stepping a 24V house bank up to power 48V DC equipment or subsystems.
• Charging a 48V lithium or lead-acid bank from a 24V source where isolation is required.
• Off-grid or mobile installations needing two electrically isolated DC voltage domains.
• Marine systems with mixed grounding where a direct bus connection would risk corrosion or faults.
• Telecom and industrial enclosures needing a regulated, isolated 48V supply from a 24V battery.

Installation notes

Fit this converter with wiring rated for the current involved, and fuse both input and output sides. Installation should be carried out by someone familiar with DC power systems, and the unit should be mounted where convection cooling can work properly. Do not exceed the rated input voltage.
