Description
Victron Energy Orion-Tr Isolated 48V to 12V 20A 240W DC-DC Converter — a professional-grade isolated power converter engineered for reliable, noise-free voltage conversion 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 10–15V to fine-tune system voltage without additional components.
- 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 48/12-20 is purpose-built for systems requiring clean, stable 12V power from a 48V battery bank. With 240W continuous output at 40°C and up to 88% efficiency, it performs reliably in real-world operating conditions without compromise.
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 compact form factor at 130 x 186 x 70mm fits neatly into tight electrical compartments on vehicles, vessels, and off-grid 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. This converter is not intended for battery charging — for charging applications, the Orion-Tr Smart is recommended.
