Detailed description

The VICTRON ENERGY Orion-Tr isolated DC converter 24/12-20A is a robust and reliable solution for systems requiring stable 12 V power from a 24 V source. Part of the Orion-Tr range, this model is among the intermediate power isolated converters, delivering 240 W of continuous power at 25 °C, maintained up to 40 °C. It differs from the Orion-Tr Smart version by focusing on general power supply rather than battery charging, for which the Smart version is optimized with specific algorithms.

Integration and flexibility

With an input voltage range of 16-35 V and a nominal output voltage of 12.2 V, adjustable from 10 to 15 V, this Orion-Tr 24/12-20A ensures flexible integration. Its ability to be connected in parallel without limit allows increasing the output current to meet higher power demands. The 200 VDC galvanic isolation between input, output, and the housing protects sensitive equipment and ensures the safety of the electrical system.

Advanced features and robustness

The converter features a remote on/off terminal, eliminating the need for a high-current switch on the input wiring and simplifying integration with existing control systems, such as an engine start/stop switch. It is protected against short circuits and high temperatures, reducing its output current if the environment exceeds 40 °C. Its IP43 protection, when the unit is installed with the terminal block facing downward, ensures adequate resistance to marine environments. Connection is via screw terminals, requiring no special tools for installation, and it includes an internal input fuse for 12 V and 24 V models, enhancing safety.

« Isolated Orion-Tr DC-DC converter: performance and safety for DC systems »

The Victron Energy Orion-Tr 24/12-20A isolated DC-DC converter is a must-have solution for complex marine electrical architectures. Its ability to convert a 24 V input into a stable, adjustable 12 V output with a continuous current of 20 A at 40°C makes it ideal for powering specific equipment or 12 V sub-networks from a main 24 V bus. The 200 VDC galvanic isolation is a major advantage, preventing ground loops and protecting sensitive electronic systems from interference and potential overvoltages. The remote on/off function simplifies integration into centralized energy management systems, while the ability to connect in parallel provides essential scalability for installations requiring increased power. Its robustness, evidenced by protection against short circuits and high temperatures, along with its IP43 rating (with proper installation), ensures operational reliability in demanding marine conditions—a standard expected from Victron Energy products.

Frequently Asked Questions

Need help? Contact us

What is the main role of the Victron Energy Orion-Tr isolated DC-DC converter 24/12-20A?

The Victron Energy Orion-Tr isolated DC-DC converter 24/12-20A is designed to provide a stable 12V power supply from a 24V source. It is ideal for powering 12V equipment in 24V systems while offering isolation for the protection of sensitive devices.

What is the input voltage range accepted by the device?

The Orion-Tr isolated 24/12-20A DC-DC converter accepts an input voltage range of 16 to 35 volts DC.

Can the output voltage of this converter be adjusted? If so, within what range?

Yes, the output voltage of this converter is adjustable. The nominal output voltage is 12.2 volts, but it can be adjusted within a range of 10 to 15 volts DC using a potentiometer.

What is galvanic isolation and what is its value on this model?

Galvanic isolation is a safety feature that prevents current from flowing directly between the input, output, and case of the converter. On this model, the galvanic isolation is 200 VDC, ensuring protection of sensitive equipment and the safety of the electrical system.

Is this converter designed for battery charging?

No, the Orion-Tr isolated 24/12-20A converter is not intended for battery charging. For this application, it is recommended to use a model from the Orion-Tr Smart range, which is optimized with specific algorithms for battery charging.

What are the built-in protections in the Orion-Tr converter?

The Orion-Tr converter is equipped with multiple protections:

Short-circuit protection.High-temperature protection, where the output current is reduced if the ambient temperature exceeds 40 °C.Under-voltage protection on the input, with a disconnect threshold at 14 V and reconnect at 15 V.

What is the energy efficiency of this converter?

The energy efficiency of this Orion-Tr isolated 24/12-20A converter is 88%.

What are the physical dimensions and weight of this converter?

The converter dimensions are 130 mm (height) x 186 mm (width) x 70 mm (depth). Its weight is 1.3 kg.

What is the operating temperature range and its resistance to environmental conditions?

The converter can operate within a temperature range from -20 °C to +55 °C. Above 40 °C, the output current is reduced by 3 % per degree Celsius. It provides IP43 protection when installed with the terminal block facing downward, making it resistant to water splashes and humidity (up to 95 % without condensation), suitable for marine environments.

How are the DC cables connected to the converter, and is any special tooling required?

DC cables are connected via screw terminals. No special tooling is required for cable installation.

What is the maximum DC cable cross-section that can be used?

The maximum recommended DC wiring cross-section for connections is 16 mm² (AWG6).

How to use the remote on/off function?

The remote on/off terminal allows you to control the inverter with a low-power switch. You can replace the jumper wire on the green connector with a switch (the switched current is less than 100 mA) or remove the jumper wire and connect the right terminal of the green connector to the positive battery pole via a switch (e.g., an engine on/off switch).

Is it possible to increase the output current by using multiple converters in parallel?

Yes, it is possible to connect an unlimited number of these converter units in parallel to increase the total output current and meet higher power requirements.

Does this model have an input fuse?

Yes, this model, with a 24 V input, has an internal input fuse. This fuse is not replaceable.

What are the recommendations for the installation location of the converter?

The converter should be installed in a cool, dry, and well-ventilated location. To maintain IP43 protection, the unit must be mounted with the terminal block facing downward.

Is this converter compatible with marine or automotive electrical systems?

Yes, due to its robustness, IP43 protection (when installed correctly), and compliance with the automotive directive ECE R10-5, this converter is perfectly suited for marine environments and automotive applications.
