Orion-Tr Smart 12/12-18A Isolated DC-DC charger

The Orion-Tr Smart 12/12-18A Isolated DC-DC Charger from Victron Energy is a high-performance device designed for charging hotel batteries from a vehicle alternator. It limits the charging current to 18A, allowing for safe and controlled charging of the service battery without the risk of damage.

Efficient charging in dual-battery systems

The Orion-Tr Smart is ideal for vehicles and boats with dual-battery systems, where the alternator powers both the starter and service batteries. With three-stage operation, the charger provides stable and efficient charging, adapting to the system's needs, making it ideal for powering devices in campers, trailers, and watercraft.

Built-in Bluetooth technology

Thanks to its Bluetooth module, the Orion-Tr Smart charger allows for full control and monitoring of its operation from a smartphone using the VictronConnect app. Users can remotely control the device and easily monitor battery charging status, giving them complete control over energy management.

Hotel Battery Protection

The Orion-Tr Smart device protects the hotel battery from overcharging, extending its lifespan. The system precisely controls current flow and adapts it to the alternator's parameters, eliminating the risk of overload. This ensures safe and reliable operation, even in harsh operating conditions.

Intelligent energy management

The Orion-Tr charger features an automatic shutdown feature when the engine is not running, preventing excessive discharge of the starter battery. Additionally, a built-in temperature sensor provides overheating protection – the charging current is automatically reduced if the temperature rises.
