Orion-Tr Smart 24 / 48-8,5A (400W) Isolated DC-DC charger

The Orion-Tr Smart 24/48-8.5A (400W) is an isolated DC-DC charger designed for 24V systems that require safe charging of 48V batteries. The device converts the 24V input voltage to the appropriate charging profile for a 48V bank, making it suitable for use where the power source is an alternator, starter battery, or other DC bus. In practice, it acts as an intelligent link between two different voltage systems, not just a simple converter.

The Smart version allows for configuration and monitoring of operation via Bluetooth in the VictronConnect app, making it easier to match parameters to the specific battery type and operating conditions. Three-stage charging allows for a more controlled process than with simple converters, and the engine detection function helps reduce unnecessary load on the power source when the vehicle or unit is idle. The 200V DC galvanic isolation improves the separation between the input and output sides, which is important in mobile systems and installations where interference, potential differences, and connection safety are important.

The device is versatile: it can operate as a DC-DC charger, but also as a standard 24V→48V voltage converter if stable power supply or indirect charging is required. This design is suitable for commercial vehicles, campers, boats, and off-grid systems where the energy source and energy storage do not share the same nominal voltage. This allows for the construction of more flexible power systems without the need to redesign the entire installation.

Typical applications and features:

• charging 48V batteries from 24V installations in vehicles, boats and autonomous systems,
• operation as an isolated DC-DC charger or as a 24V→48V voltage converter,
• configuration and monitoring via Bluetooth in the VictronConnect application,
• three-stage charging process for more controlled energy replenishment,
• engine operation detection and automatic shutdown when the charging source is not working,
• 200V DC galvanic isolation supporting the separation of circuits and reducing problems with potential differences,
• a solution for users who need to connect two different voltage systems without interfering with the main installation.

In terms of compatibility, the Orion-Tr Smart 24/48-8.5A (400W) is a good choice for installations based on 48V batteries, where the power source remains a 24V system. It works well in both mobile and stationary applications, especially where automation, configurability, and maintaining galvanic isolation between circuits are important. This solution is for those who want to organize their 24/48V charging and have real control over it without the need for multiple additional devices.

During installation, it's important to ensure proper input and output connections, adequate cable protection, and operating conditions consistent with the DC installation. In practice, the charger performs best when mounted as close as possible to the source or battery bank, with operating parameters previously set in the VictronConnect app for the specific battery type and usage.

Technical data

The kit includes a device for building or expanding a 24/48V system, which can be customized to your specific system via Bluetooth. Before starting, it's worth checking voltage compatibility, engine detection, and wiring and safety requirements to ensure the charger's full capabilities are utilized in your specific installation.
