Victron Orion-TR 24/24-12A (280W) Isolated DC-DC Converter

Orion-TR 24/24-12A (280W) Isolated DC-DC Converter

Isolated Model - separate in and out (-) leads

Remote On/Off Terminal

The remote on/off terminal eliminates the need for a high current switch in the input wiring. The remote on/off can be operated with a low power switch or for example the engine run/stop switch.

All Models Are Short Circuit Proof and Can Be Paralleled to Increase Output Current

An unlimited number of units can be connected in parallel.

High Temperature Protected

The output current will reduce at high ambient temperatures.

IP43 Protection

When installed with the screw terminals oriented downward.

Screw Terminals

No special tools are needed for installation.

Input Fuse (not replaceable)

On 12 V and 24 V input models only.

The Victron Orion-TR 24/24-12A (280W) is a reliable isolated DC-DC converter designed for versatile power conversion applications. This model features a galvanic isolation of 200 VDC between input, output, and case, ensuring safe and stable operation in complex electrical environments. With a nominal output voltage of 24.2 V and an adjustable range from 20 to 30 V, it provides flexible voltage regulation suitable for various industrial and vehicle applications. The converter supports a continuous output current of 12 A at 40°C and can deliver up to 15 A for short durations, making it suitable for demanding power loads. Its high efficiency of 89% helps minimize energy loss, while the low output noise of 2 mV rms ensures clean power delivery for sensitive electronics.

The Orion-TR converter includes a remote on/off terminal, eliminating the need for high-current switches in the input wiring. This feature allows simple activation and deactivation using low-power switches or existing engine control systems, enhancing installation flexibility. The unit is protected against short circuits, and multiple units can be paralleled without limitation to increase total output current, providing scalability for larger systems. High ambient temperatures are managed through thermal protection, which reduces output current to prevent overheating, ensuring durability in challenging environments. Its IP43 protection rating offers resistance against dust and water ingress when installed with screw terminals downward.

Designed for ease of installation, the converter uses screw terminals that do not require special tools and supports a maximum cable cross-section of 16 mm AWG6. The unit's compact dimensions and lightweight design facilitate straightforward mounting in confined spaces. The input voltage range of 16-35 V allows operation across various power sources, with over-voltage and under-voltage protections included. Certified to EN 60950 safety standards and compliant with automotive directives (ECE R10-5), this converter is suitable for automotive, marine, and industrial applications.
