Victron Orion-TR 12/48-8A (380W) Isolated DC-DC Converter

The Orion-TR 12/48-8A (380W) Isolated DC-DC Converter is a reliable and efficient power solution designed specifically for marine and boating applications. Engineered to provide stable voltage and protect your boat’s electrical systems, this converter ensures optimal performance whether you're cruising the open seas or navigating coastal waters.

Key Features

Remote On/Off Terminal

Eliminate the need for a high-current switch in your boat’s input wiring. The remote on/off terminal allows operation with a low-power switch, such as the engine run/stop switch, enhancing convenience and safety onboard.

Short Circuit Proof and Paralleling Capability

All models are designed to be short circuit proof and can be paralleled to increase output current. This flexibility allows you to connect an unlimited number of units, ensuring scalable power solutions for larger marine electrical systems.

High Temperature Protection

Operating in marine environments can subject electronics to varying temperatures. The Orion-TR reduces output current at high ambient temperatures, safeguarding the converter and connected devices from overheating.

IP43 Protection Rating

With an IP43 rating, this converter is protected against solid objects larger than 1mm and water spray from any direction when installed with the screw terminals oriented downward, making it suitable for the humid and wet conditions typical on boats.

Easy Installation with Screw Terminals

No special tools are required for installation. The screw terminals provide a secure and straightforward connection method, ideal for the dynamic environment of marine applications.

Built-in Input Fuse

Models with 12V and 24V inputs include a non-replaceable input fuse, adding an extra layer of protection to your boat’s electrical system.

Adjustable Output Voltage

Customize the output voltage between 40V and 60V to meet your specific marine electrical requirements. Please note, it is not intended for battery charging—consider using an Orion-Tr Smart model for that purpose.
