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 intelligent, efficient charging.

The primary 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 supply 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 variation within the specified 16–35V range.

Bulk (bulk charge): The charger delivers maximum current to quickly 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 (maintenance): A maintenance 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 energy conversion.

Yes, the Orion-Tr Smart charger features extensive electronic protection. It is protected against overheating (with power reduction), overload, short circuits, and connector overheating.

The charger has an IP43 ingress 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 intelligent 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 engine running detection, configurable via the VictronConnect app. This eliminates the need for additional wiring, external sensors, or CAN-bus system modifications.

The charger is equipped with integrated Bluetooth Smart, allowing it to be configured, monitored, and updated wirelessly via the VictronConnect application. This application 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 avoid 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, consider mechanical air extraction and ensure adequate ventilation. The charger is protected against overheating and reduces its output if the temperature becomes too high.
