Orion-Tr Smart 24/12-20A

This is an isolated DC-DC converter/charger designed to recharge a 12V auxiliary or service battery from a 24V system, such as an alternator or starter battery. It is particularly suited to modern vehicles and provides smart, efficient charging.

The main function is to efficiently charge a 12V auxiliary battery from a 24V power source while ensuring electrical isolation between the two systems. It can also serve as a fixed-voltage DC-DC power supply.

The charger is optimized to extend the lifespan of lead-acid batteries (flooded, Gel, AGM) and lithium batteries (LiFePO4) thanks to its three-stage adaptive charging algorithm.

It has a continuous output capacity of 20A up to 40°C, delivering up to 240W. It can also provide a peak current of 25A for 10 seconds.

Yes, this device can be configured to operate as a fixed-voltage DC-DC power supply. In this mode, it maintains a stable output regardless of load or input voltage variations within the specified 16-35V range.

Bulk (bulk charge): The charger delivers maximum current to rapidly recharge the batteries. Absorption: The charger switches to constant voltage mode. The duration is automatically adjusted based on depth of discharge for lead-acid batteries, and is fixed (default 2 hours) for lithium batteries. Float (trickle): A float voltage is applied to keep the battery in a fully charged state. A new charge cycle is triggered if the battery voltage drops significantly.

The supported input voltage range for the charger is 16V to 35V DC. The charger is designed for nominal 24V input systems.

The nominal output voltage of the Orion-Tr Smart 24/12-20A charger is 12V DC.

The charger delivers an efficient energy efficiency of 88%, ensuring optimized power conversion.

Yes, the Orion-Tr Smart charger is equipped with extensive electronic protection. It is protected against overheating (with power reduction), overcharging, short circuits, and overheating of connectors.

The charger has an IP43 protection rating.

Yes, it is normal for the Orion-Tr Smart DC-DC charger to emit a noticeable odor when operating at or near its maximum power and heating up. This odor is not harmful to health.

Yes, it is specifically designed to be compatible with smart alternators (Euro 5 and 6) that deliver variable output voltage and can shut down to optimize fuel consumption. It includes an engine-running detection mechanism.

The Orion-Tr Smart DC-DC charger automatically separates the starter battery and the service battery when the engine is not running. This prevents the starter battery from discharging.

No, the charger includes software-based detection of the engine running, configurable via the VictronConnect app. This eliminates the need for additional wiring, external sensors, or interference with the vehicle’s CAN-bus system.

The charger is equipped with integrated Bluetooth Smart, allowing wireless configuration, monitoring, and firmware updates via the VictronConnect app. This app is available for Apple and Android smartphones and tablets.

The charger must be mounted vertically on a non-flammable surface, with the power terminals facing downward. It is recommended to install it near the battery, but never directly above it to prevent damage from battery gases. A minimum clearance of 10 cm above and below is required for optimal cooling.

The charger has a remote on/off function. You can activate or deactivate it via the dedicated remote on/off connector or through the VictronConnect app. This allows easy integration into automation systems or with a wired switch.

Yes, but it is normal for the charger to heat up during operation. In very hot environments, mechanical air extraction and adequate ventilation should be considered. The charger is protected against overheating and reduces its output if the temperature becomes too high.
