Detailed description

Le convertisseur isolé Orion-Tr 24/12-9A (110W) DC-DC de VICTRON ENERGY est conçu pour les systèmes nécessitant une conversion de tension de 24 V vers 12 V, avec une isolation galvanique. Il est adapté pour alimenter des équipements 12 V à partir d'une source de batterie 24 V, éliminant les courants parasites et les interférences électriques. Ce modèle de 110 W se positionne comme une solution compacte au sein de la gamme Orion-Tr, qui inclut également des versions de 250 W et 400 W pour des besoins en puissance plus élevés.

Performance Électrique et Fiabilité

Ce convertisseur fonctionne avec une plage de tension d'entrée de 16-35 V DC, et assure une tension de sortie nominale de 12,2 V. La tension de sortie est réglable entre 10 et 15 V via un potentiomètre, ce qui permet une adaptation précise aux exigences de charge ou, selon le manuel d'utilisation en français, de l'utiliser pour charger une batterie de démarrage ou de servitude de 12 V dans un système 24 V. Il délivre un courant continu de 9 A à 25 °C, avec un courant de sortie maximum de 12,5 A pendant 10 secondes. Son rendement est de 85 %, et il affiche une isolation galvanique de 200 V DC entre l'entrée, la sortie et le boîtier, garantissant la sécurité et la stabilité du système.

Fonctionnalités et Intégration Système

L'Orion-Tr 24/12-9A intègre une borne marche/arrêt à distance, simplifiant le contrôle sans nécessiter d'interrupteur de forte intensité sur le câblage d'entrée. Pour une flexibilité accrue, un nombre illimité d'unités peut être mis en parallèle afin d'augmenter le courant de sortie total. La protection IP43 est assurée si l'unité est installée avec les borniers orientés vers le bas, protégeant contre la poussière et les projections d'eau. Il est protégé contre les courts-circuits, les surcharges et les températures élevées, réduisant automatiquement le courant de sortie en cas de surchauffe. Les borniers à vis facilitent l'installation sans outils spéciaux. À noter que pour des applications de charge de batterie plus avancées, la gamme Orion-Tr Smart de Victron Energy offre des fonctionnalités dédiées.

Expert opinion

« Orion-Tr 24/12-9A DC-DC converter: reliable DC-DC conversion for your isolated systems »

The Victron Energy Orion-Tr 24/12-9A converter provides a reliable solution for integrating 12 V equipment into a 24 V electrical system. Its primary function is to deliver a stable, isolated 12 V output, which is critical to prevent ground loops and electrical interference—especially in marine environments or recreational vehicles where electrical systems can be complex. It is ideal for powering navigation equipment, lighting, or other small 12 V consumers without disrupting the main 24 V system.

From an installation standpoint, its screw terminals simplify wiring. The remote on/off function is a significant advantage, allowing easy integration into an existing control circuit—for example, via an engine ignition switch—without handling high currents. While this 110 W model is designed for moderate loads, its ability to be wired in parallel offers flexibility to increase available power if needs change. It is important to note that its IP43 protection rating requires specific orientation (terminals facing downward) to ensure resistance to water splashes, a practical consideration for mounting location. For applications requiring more sophisticated battery charge management, the Orion-Tr Smart series is more suitable, whereas this model excels at providing stabilized current to direct consumers.

Frequently Asked Questions

Need help? Contact us

What is the primary function of the Orion Tr 24/12-12A converter?

The primary function of this converter is to convert a 24 V DC input into a 12 V DC output. It provides galvanic isolation between input and output, which is essential to prevent stray currents and electrical interference in marine or automotive systems.

What are the input and output voltages of this converter?

This converter is designed for a nominal input voltage of 24 V DC, with an operating range of 16 to 35 V DC. The nominal output voltage is 12.2 V DC and is adjustable.

What is the continuous output power of this model?

The Orion Tr 24/12-9A converter can provide a continuous output power of 110 W at an ambient temperature of 25 °C. This power is reduced to 85 W if the ambient temperature reaches 40 °C.

What is the continuous output current this converter can provide?

The DC output current of this converter is 9 A at an ambient temperature of 25 °C. It can also supply a maximum output current of 12.5 A for 10 seconds.

What is galvanic isolation and what is its advantage?

Galvanic isolation is an electrical separation between two circuits that prevents unwanted DC current from flowing while allowing energy or signals to be transferred. In the case of this converter, it is 200 V DC between the input, output, and housing, providing protection against ground loops, reducing electrical interference, and improving system safety.

Is the output voltage of this converter adjustable?

Yes, the output voltage of this converter is adjustable. It can be set between 10 and 15 V DC using an integrated potentiometer. The default value is 12.2 V.

What is the efficiency of this DC-DC converter?

This converter displays an efficiency of 85%. High efficiency means less energy loss as heat and more efficient use of battery power.

Is this converter equipped with an internal fuse?

Yes, Orion-Tr converter models with a 12 V or 24 V input, like this one, have an internal input fuse. This fuse is not user-replaceable.

What are the physical dimensions and weight of the converter?

The dimensions of the Orion Tr 24/12-9A converter are 100 x 113 x 47 mm (height x width x depth). Its weight is 0.42 kg.

What protections are built into the Orion Tr 24/12-9A converter?

This converter integrates multiple protections to ensure system safety and reliability:

Output short-circuit protection.Overload protection.High-temperature protection with automatic output current reduction in case of overheating.Input undervoltage protection with automatic disconnection and reconnection.

How does the remote on/off function work?

The on/off remote function is controlled by a dedicated socket. It allows you to operate the inverter using a low-power switch (switched current below 100 mA) or, for example, via the engine's on/off switch. This eliminates the need for a high-current switch on the input wiring.

Is it possible to connect multiple converters in parallel?

Yes, an unlimited number of these converter units can be connected in parallel to increase the total output current. It is important to always set the output voltage of each unit before connecting them in parallel.

What is the recommended mounting orientation for IP43 protection?

To achieve IP43 protection, which guards against dust and water spray, the unit must be installed with the terminal blocks facing downward.

Which types of terminals are used for DC connections?

The converter uses screw terminals for DC connections. No special tools are required for cable installation.

What is the maximum cable cross-section accepted by the terminal blocks?

The terminals on this converter accept a maximum cable cross-section of 6 mm² (AWG10).

What are the operating temperature and humidity ranges?

This 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. The maximum permitted humidity is 95 % without condensation.

Can this converter be used to charge batteries?

Although the output voltage is adjustable, this converter is not primarily designed for battery charging. For optimal charging and advanced features, it is recommended to use a converter from the Victron Energy Orion-Tr Smart range, specifically designed for this purpose.

Is this converter suitable for powering sensitive electronic equipment?

Yes, thanks to its 200 V DC galvanic isolation and low output noise (2 mV rms), this converter is suitable for powering sensitive electronic equipment by reducing interference and ensuring stable power supply.

What is the acceptable input voltage range for the device?

This converter accepts an input voltage range of 16 to 35 V DC. It also features a low-voltage disconnect threshold at 14 V and reconnect threshold at 15 V to protect the input source.
