Detailed description

The Victron Energy Orion Tr 24/12-9A (110W) isolated DC-DC converter is a robust and reliable power conversion solution designed to power 12V devices from 24V battery systems. This 110W model, with a continuous output current of 9A, is a key choice for marine applications, utility vehicles, RVs, and trucks requiring stable and protected power supply. It is part of the Orion Tr range, known for its reliability in demanding environments. While effective for general power supply, for advanced battery charging functions, the Orion Tr Smart range offers optimized charge management capabilities and Bluetooth connectivity.

Galvanic Isolation and System Flexibility

The Orion Tr 24/12-9A features 200 V DC galvanic isolation between input, output, and case, effectively protecting connected equipment from ground loops, voltage spikes, and electrical interference. Its 16-35V DC input voltage range and adjustable 10-15V DC output voltage (nominal 12.2V DC) allow precise adaptation to specific needs. The remote on/off function eliminates the need for a high-current switch on the input wiring and can be activated by a low-power switch or engine contact. This flexibility sets it apart from more basic converters, offering simplified system integration.

Rugged Design and Advanced Protection

Built for durability, this device features a vibration-resistant aluminum housing and is protected against short circuits and overloads. It can operate in a temperature range of -20 to +55 °C, with a 3 % power reduction per °C above 40 °C. Its IP43 protection is ensured if the terminal block is oriented downward, providing resistance to water spray. The Victron Energy Orion Tr stands out for its ability to be paralleled with an unlimited number of units to increase output current, a key technical feature for scalable installations. The screw terminals facilitate tool-free installation, with a maximum cable cross-section of 6 mm² (AWG10). Its 85 % efficiency ensures efficient energy conversion, minimizing losses.

Expert opinion

« Orion TR 24/12-9A: the isolated solution for reliable 24V to 12V conversion »

The Victron Energy Orion TR 24/12-9A (110W) DC-DC converter is a critical component for any 24V marine or onboard electrical system requiring stable and secure 12V power. Its key advantage is 200V DC galvanic isolation, essential for eliminating interference and protecting sensitive electronic equipment from ground loops—a common issue in marine environments. The adjustable output voltage range (10–15V) provides valuable flexibility, particularly for powering specific devices or charging a small 12V backup battery. Its design allows unlimited parallel connection of units, ensuring system scalability. The on/off remote terminal simplifies integration with existing energy management systems or engine switches. The robust aluminum housing and IP43 protection (with terminals facing downward) ensure operational reliability even in harsh conditions. It is a sound choice for reliable DC-DC conversion, though for advanced battery charging management, the Orion TR Smart series is recommended.

Frequently Asked Questions

Need help? Contact us

What is the primary function of the Victron Energy Orion TR 24/12-9A converter?

The Victron Energy Orion TR 24/12-9A converter is designed to convert a 24V DC input to a 12V DC output. It powers 12V devices from a 24V battery or power system while providing electrical isolation between input and output.

What is galvanic isolation and why is it important for this converter?

The 200 V DC galvanic isolation means there is no direct current path between the converter’s input, output, and case. This feature is critical because it protects connected equipment from ground loops, voltage spikes, and electrical interference, thereby improving the safety and reliability of the entire system.

What is the continuous output power of this converter at 25°C?

The continuous output power of this inverter is 110 W when operating at an ambient temperature of 25°C.

What is the nominal DC output current of this model?

The nominal continuous output current of the Orion Tr 24/12-9A is 9 A at the nominal output voltage and at 25°C.

What is the efficiency of this DC-DC converter?

The efficiency of this DC-DC converter is 85%.

What are the physical dimensions and weight of the Orion Tr 24/12-9A converter?

The converter has the following dimensions (height x width x depth): 100 x 113 x 47 mm. Its weight is 0.42 kg.

Does the converter have an internal fuse?

Yes, this converter model (with a 24V input) has an internal input fuse. It is not user-replaceable.

What is the operating temperature range of the device?

The device can operate within a temperature range from -20°C to +55°C. Note that a 3% reduction in output current is applied per degree Celsius above 40°C.

Is the converter protected against high temperatures?

Yes, the converter is protected against high temperatures. If the ambient temperature is high, the output current will be automatically reduced to prevent the device from overheating.

Can this converter be used to charge batteries?

Although the output voltage is adjustable, this Orion Tr model is not specifically designed for optimal battery charging. For advanced battery charging functions, it is recommended to use the Victron Energy Orion Tr Smart range, which offers optimized charge management capabilities.

What is the input voltage range accepted by this converter?

This converter accepts an input voltage range of 16 V to 35 V DC.

What is the nominal output voltage of the device?

The nominal output voltage of this converter is 12.2 V DC.

Can I adjust the output voltage of this converter? If so, within what range?

Yes, the output voltage is adjustable. You can set it within a range from 10 V to 15 V DC using the potentiometer located on the device.

Is it possible to connect multiple Orion Tr converters in parallel to increase the output current?

Yes, it is entirely possible to connect an unlimited number of Orion Tr units in parallel to increase the total output current. Always ensure you adjust the output voltage of each converter before connecting them in parallel.

What happens if the input voltage drops below the recommended threshold?

If the input voltage drops below 14 V, the converter will disconnect (undervoltage disconnect threshold) to protect the system. It will restart automatically when the input voltage reaches 15 V (undervoltage reconnect threshold).

How does the remote on/off function work?

The remote on/off function eliminates the need for a high-current switch on the input wiring. It can be operated by replacing the jumper wire on the green connector with a low-power switch (switched current less than 100 mA), or by connecting the right terminal of the green connector to the positive battery terminal via a switch (e.g., the engine on/off switch).
