Orion-Tr Smart 24/24-17A

The Victron Energy Orion-Tr Smart 24/24-17A charger is an uninsulated DC-DC charger designed for dual-battery systems, particularly in vehicles and boats. It can operate as a battery charger with a 3-stage adaptive charging algorithm or as a fixed-output power supply. It is especially useful for ensuring correct charging of service batteries, even with smart alternators or long cable lengths.

This DC-DC charger provides continuous output power of 400 W at 40 °C. At an ambient temperature of 25 °C, it can reach continuous output power of 480 W.

The Orion-Tr Smart 24/24-17A is designed for 24 V systems. It accepts an input voltage range of 16 to 35 V. The nominal output voltage is 24.2 V and can be adjusted within a range of 18 to 30 V.

The Victron Energy Orion-Tr Smart 24/24-17A charger delivers a continuous output current of 17 A at 40 °C and at its nominal output voltage.

The Victron Energy Orion-Tr Smart 24/24-17A is a non-isolated DC-DC charger. This means there is no galvanic isolation between the input and output.

Yes, the Orion-Tr Smart can be used as a power supply. In this mode, the output voltage remains stable, regardless of the load applied or variations in the input voltage (within the specified range).

The Orion-Tr Smart’s three-stage adaptive charging algorithm is optimized for lead-acid (flooded, gel, AGM) and lithium (LiFePO4) batteries.

Bulk (bulk charge): The charger delivers the maximum charging current to rapidly recharge the batteries. Absorption: When the battery voltage reaches the set absorption voltage, the charger switches to constant voltage mode. For lead-acid batteries, the absorption time is adjusted based on the depth of discharge. For lithium batteries, the absorption time is fixed, by default at 2 hours. Float (trickle): A float voltage is applied to maintain the battery in a fully charged state. A new charge cycle is triggered if the battery voltage drops significantly.

Yes, the Orion-Tr Smart 24/24-17A is compatible with Euro 5 and Euro 6 smart alternators. It includes an engine-running detection mechanism that prevents the starter battery from discharging when the alternator is not supplying power.

The Orion-Tr Smart charger features an integrated engine-running detection mechanism. This function allows it to supply power only when the engine is running, preventing the starter battery from discharging and avoiding voltage drops aboard the vehicle. No separate engine-running sensor or CAN-bus system modification is required.

Yes, an unlimited number of Orion-Tr Smart units can be connected in parallel. This feature allows increasing the total output current for higher charging requirements.

Yes, the Orion-Tr Smart 24/24-17A charger is equipped with extended electronic protections, including protection against overcharging, short circuits, and overheating. In case of high ambient temperature, the output current will be reduced.

The operating temperature range of the Orion-Tr Smart is -20 to +55 °C. Above 40 °C, the output current is reduced by 3 % per degree Celsius.

For optimal installation, the charger must be mounted vertically on a non-flammable surface, with the power terminals facing downward. It is recommended to leave a minimum clearance of 10 cm above and below the unit to ensure adequate cooling. Install it near the battery, but never directly above to avoid damage from battery gases.

Use flexible multistrand copper cables for battery connections. The individual strand diameter of the cable must not exceed 0.4 mm or have a cross-sectional area of 0.125 mm² (AWG26). The maximum cable cross-section is 16 mm² (AWG6). An installation must always include a fuse in accordance with the manufacturer's recommendations for circuit protection.

Yes, the Orion-Tr Smart is equipped with a remote on/off function. A switch or relay contact can be connected to a two-pole connector to remotely turn the charger on or off. This function can also be controlled via the VictronConnect app.

Yes, the VictronConnect app is essential for configuring, monitoring, and updating the Orion-Tr Smart charger. With built-in Bluetooth Smart technology, you can access key data, adjust settings, and receive alerts directly from your smartphone, tablet, or other device.

No, the product is not protected against reverse polarity. It is crucial to check the polarity before and during the battery connection to avoid any damage.

The Orion-Tr Smart 24/24-17A charger has an IP43 protection rating for electronic components when installed with screw terminals oriented downward. The connection area has an IP22 protection rating.

No, the Orion-Tr Smart charger is not equipped with a VE.Direct port. Configuration and monitoring are done via Bluetooth Smart and the VictronConnect application.
