Victron Energy Orion-Tr 48/12-20A (240W) Isolated DC-DC Converter

Technical Specifications  User manual

The Victron Energy Orion-Tr 48/12-20A converts a 32–70V DC input into a stable, adjustable 12V output for vehicle, marine, and off-grid electrical systems. Galvanic isolation separates the input and output circuits, while remote on/off control, short-circuit protection, and parallel operation provide flexibility for demanding installations.

FEATURES

• 48V to 12V conversion: Provides a nominal 12.2V output, adjustable from 10V to 15V.

• 20A continuous output: Supplies up to 20A at 40°C under specified operating conditions.

• Galvanic isolation: Provides 200V DC isolation between input, output, and case.

• Remote on/off control: Allows operation through a low-current switch without a high-current input switch.

• Parallel operation: Connect multiple units to increase available output current.

• Integrated protection: Short-circuit protection and thermal protection with automatic output-current reduction at high temperatures.

• Flexible installation: Screw terminals simplify wiring; IP43 protection applies when installed with terminals facing downward.
