Victron Energy Orion-Tr 24/48-2.5A (120W) Isolated DC-DC Converter

Technical Specifications  User manual 

The Victron Energy Orion-Tr 24/48-2.5A is an isolated DC-DC converter that steps up a 24V DC supply to an adjustable 48V-class output. Designed for vehicle electrical systems, marine installations, and off-grid applications, it delivers stable power with galvanic isolation between input and output. Remote on/off control, short-circuit protection, and the ability to connect multiple units in parallel provide added flexibility for custom electrical systems.

FEATURES

• Voltage conversion: Steps up 24V DC to an adjustable 40–60V DC output.

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

• Remote on/off: Allows control using a low-power switch or compatible engine signal.

• Parallel operation: Multiple units can be connected in parallel to increase output current.

• Short-circuit protection: Designed to protect against output short circuits.

• Thermal protection: Automatically reduces output current at high ambient temperatures.

• IP43 protection: Applies when installed with the screw terminals facing downward.

• Simple connections: Screw terminals require no special installation tools.
