Victron Energy Orion-TR 24/12-20A Isolated DC-DC Converter

Orion-TR 24/12-20A (240W) 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 Energy Orion-TR 24/12-20A DC-DC converter is a reliable power conversion solution designed for automotive and industrial applications. With an input voltage range of 16 to 35 V, it efficiently converts 24 VDC to a stable 12.2 VDC output, making it ideal for powering sensitive electronics. Its high efficiency of 88% ensures minimal energy loss during operation, and the converter can deliver continuous output currents up to 20 A, with short-term peaks reaching 25 A for demanding loads. The unit features galvanic isolation of 200 VDC between input and output, providing safety and reducing electromagnetic interference. It includes a remote On/Off terminal that allows control via low-current switches or engine control systems, simplifying integration into various setups.

Constructed with a robust design, the Orion-TR converter is short circuit proof and can be paralleled indefinitely to increase total output current, making it suitable for expanding power systems. Its IP43 ingress protection, when installed with screw terminals downward, offers resistance against dust and limited water exposure, ensuring durability in challenging environments. The device also incorporates high-temperature protection, reducing output current in response to elevated ambient temperatures to prevent overheating and maintain longevity. Its compact dimensions and screw terminal connections facilitate straightforward installation without special tools, and the unit’s compliance with safety standards such as EN 60950 and automotive directives ensures reliable operation across multiple sectors.

Additional features include adjustable output voltage within a range of 10 to 15 V, making it adaptable to different system requirements, although it is not intended for battery charging. The converter's low no-load input current (<100 mA) and minimal power consumption when disabled (<200 μA) contribute to energy efficiency. Designed to operate in temperatures from -20°C to +55°C, it withstands various environmental conditions, provided humidity stays below 95% non-condensing. The product comes with comprehensive documentation and a warning regarding chemical exposure, adhering to safety and environmental standards, making the Victron Energy Orion-TR 24/12-20A DC-DC converter an excellent choice for powering 12 V systems from 24 V sources in demanding applications.
