Description
Victron Energy Orion-Tr Isolated 48V to 48V 6A 280W DC-DC Converter — a professional-grade isolated power converter engineered for reliable, noise-free same-voltage DC conversion with full galvanic isolation in off-grid, marine, and mobile applications.
Key Features
- Galvanic Isolation: Provides 200VDC isolation between input, output, and case, eliminating ground loops and protecting sensitive equipment.
- Remote On/Off Control: Eliminates the need for a high-current input switch, operable via a low-power switch or engine run/stop signal.
- Adjustable Output Voltage: Output is fully adjustable between 40–60V, and can also be configured for battery charging applications.
- Parallel Operation: An unlimited number of units can be connected in parallel to scale output current as system demands grow.
- Short Circuit Proof: Built-in short circuit and high temperature protection ensures safe, uninterrupted operation in demanding environments.
The Orion-Tr 48/48-6 is ideal for systems requiring fully isolated 48V power distribution from a primary 48V source, keeping sensitive loads protected from noise and ground faults. With 280W continuous output at 40°C and up to 89% efficiency, it delivers outstanding performance across real-world operating conditions.
Installation is straightforward thanks to tool-free screw terminals accepting cable up to 16mm² (AWG6) and an IP43-rated enclosure when mounted with terminals facing downward. The robust form factor at 130 x 186 x 70mm fits neatly into electrical compartments on vehicles, vessels, and off-grid energy systems.
Compliant with EN 60950, EN 61000-6-3, EN 55014-1, and Automotive Directive ECE R10-5, the Orion-Tr meets stringent safety, emission, and immunity standards. Unlike previous models in this series, this unit supports adjustable output voltage suitable for battery charging applications.
