Victron Orion-TR DC-DC Converter - 12 VDC to 12 VDC - 18AMP Isolated

The Orion-TR 12/12-18A (220W) Isolated DC-DC Converter is expertly designed for marine and boating applications, providing reliable power conversion essential for your vessel's electrical systems. With robust features tailored to withstand the demanding marine environment, this converter ensures consistent performance and safety on every voyage.

Key Features

Remote On/Off Terminal

The remote on/off terminal simplifies your wiring setup by eliminating the need for a high current switch in the input wiring. Easily control the converter with a low power switch, such as your boat’s engine run/stop switch, enhancing convenience and safety.

Short Circuit Proof & Parallel Operation

All models are short circuit proof and can be paralleled to increase the output current. This flexibility allows you to connect an unlimited number of units in parallel, ensuring your power needs are met efficiently.

High Temperature Protection

Designed for harsh marine environments, the converter features high temperature protection. The output current automatically reduces at high ambient temperatures to prevent overheating and ensure longevity.

IP43 Protection

With an IP43 rating, the Orion-TR is safeguarded against solid objects and water spray when installed with the screw terminals oriented downward, making it ideal for marine installations.

Easy Installation with Screw Terminals

Installation is straightforward with screw terminals, requiring no special tools. This feature simplifies the setup process, saving you time and effort during installation.

Built-in Input Fuse

Equipped with a non-replaceable input fuse for 12V and 24V models, the converter adds an extra layer of protection, enhancing the safety of your boat’s electrical system.

Adjustable Output Voltage

Customize the output voltage between 10V and 15V to suit your specific marine equipment needs. Note that this model is not intended for battery charging; consider using an Orion-Tr Smart for that purpose.
