Victron Orion-Tr DC-DC Converter 24/48-8.5A 400W

Product Description

The Victron Orion-Tr 24/48-8.5A 400W is a high-performance isolated DC-DC converter that safely steps up a 24 V bus to a regulated 48 V line. It incorporates 200 V galvanic isolation between input, output, and enclosure, IP43 protection, and a remote on/off terminal for easy control from an ignition contact, relay, or controller. The output voltage is nominally 48.2 V and can be adjusted between 40 and 60 V, allowing compensation for cable drops or adaptation to sensitive electronics requirements. With 8.5 A continuous at 40 °C (400 W) and up to 480 W at 25 °C, it provides a robust and silent source for communications, networks, PLCs, and 48 V lighting in vehicles, marine, and professional solar systems. :contentReference[oaicite:0]{index=0}

Advantages or Benefits

• Powers 48 V equipment from a 24 V system with flawless regulation, preventing restarts and errors due to voltage drop.
• Clean and safe integration thanks to galvanic isolation and remote switching, allowing control from the main system. :contentReference[oaicite:7]{index=7}
• Reliable operation in demanding environments due to thermal management with automatic power reduction and robust IP43 design. :contentReference[oaicite:8]{index=8}
• True scalability: connect multiple units in parallel if the project requires more current at 48 V. :contentReference[oaicite:9]{index=9}
• Professional installation with large-section terminals that minimize losses over long runs.

Purpose or Applications

Ideal for intervention vehicles and campers with 48 V loads, bridge electronics and onboard communications, CCTV/IoT systems, networks, and light automation. In off-grid solar, it is perfect when the main battery bank is 24 V and a stable 48 V line is needed for specific devices.

Technical Specifications

Data verified in the official datasheet for Orion-Tr isolated converters (360–400 W series).

Compatibilities

Can be connected in parallel with other Orion-Tr units to increase current. It is not a battery charger; for DC-DC charging use the Orion-Tr Smart range with specific charging profiles. :contentReference[oaicite:11]{index=11}

The Victron Orion-Tr 24/48-8.5A 400W offers powerful, stable, and safe 24→48 V conversion, with fine adjustment, isolation, and professional reliability for the most demanding applications.
