Orion-Tr Smart 48/24-16A

This is an isolated DC-DC charger designed for dual-battery systems in modern vehicles and boats. It provides adaptive charge management and stable power supply, offering voltage conversion with galvanic isolation for increased safety and reduced electrical interference in complex environments.

The Orion-Tr Smart 48/24-16A provides a nominal power of 380W. It can deliver up to 16A continuously at an ambient temperature of 40°C.

The charger has a nominal input voltage of 48V, with an operating range from 32V to 70V. It provides an output voltage of 24V, which is adjustable between 20V and 30V.

Yes, the Orion-Tr Smart 48/24-16A is compatible with smart alternators (Euro 5/6). It includes engine-stop detection to ensure controlled charging and prevent discharge of the starter battery when the alternator is not supplying power.

The charger uses a three-stage adaptive charging algorithm:

Bulk (Fast charge): The controller delivers maximum charge current to quickly recharge the batteries.

Absorption: Once the battery voltage reaches the absorption voltage setting, the controller switches to constant voltage mode. For lead-acid batteries, the absorption time is adjusted after deep discharges, and for lithium batteries, it is set to 2 hours by default.

Float (Maintenance): A float voltage is applied to the battery to keep it fully charged. A new charge cycle is triggered if the battery voltage drops significantly.

Yes, the Orion-Tr Smart 48/24-16A is designed to optimize the lifespan of lead-acid and lithium batteries thanks to its adaptive charging algorithm. The mode (fixed or adaptive) and absorption time are configurable via the VictronConnect application.

The charger includes multiple extended electronic protections:

Short-circuit protection.Overload protection.Overheat protection with power reduction (derating).Connector overheat protection.Input voltage lockout.

The charger is configured and monitored via the VictronConnect app, thanks to the integrated Bluetooth Smart connectivity. The app is available for Apple and Android smartphones and tablets, allowing you to customize settings, monitor live data, and update the firmware.

No, the charger should be mounted vertically on a non-flammable surface, with the power terminals facing downward to ensure optimal cooling. A minimum clearance of 10 cm must be maintained above and below the unit.

For battery connections, use flexible multi-strand copper cables. Individual strand diameter must not exceed 0.4 mm (0.016 in) or have a cross-sectional area of 0.125 mm² (AWG26). Installation must also include a fuse compliant with the manual’s recommendations, for which a recommendation table is provided in the technical documentation.

Engine stop detection is an integrated mechanism that allows the charger to supply power only when the vehicle's engine is running. This prevents the starting battery from discharging when the alternator is not providing power and avoids the vehicle's onboard voltage from dropping too low. No separate engine running sensor or CAN-bus system intervention is required.

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

Yes, for systems requiring higher load capacity, an unlimited number of Orion-Tr Smart units can be connected in parallel to increase the total output power.

The charger should be mounted near the battery, but never directly above it. This prevents potential damage from battery gas release during charging.

The device operates with a nominal input voltage of 48V and supports an input voltage range from 32V to 70V.

The nominal output voltage is 24V, but it is adjustable via the VictronConnect app within a range of 20V to 30V. This allows flexibility to adapt to different battery types or power requirements.

The remote on/off function allows you to turn the charger on and off remotely. This can be done either via the dedicated remote on/off connector or via the VictronConnect app. It is useful for a wired switch or automatic control by a battery management system (BMS).

The Orion-Tr Smart DC-DC Charger separates the starting battery from the service battery when the engine is not running. This prevents the service battery from discharging the starting battery.

Yes, it is crucial to read the manual carefully before installation and use. Key precautions include:

Install the product in a heat-resistant environment and ensure adequate ventilation.Never place the charger directly on the battery.Avoid sparks near the battery.Check polarity before and during battery connection, as the product is not protected against reverse polarity.

The charger is equipped with an input voltage lock-out function. It will shut down if the input voltage drops below a configurable lock-out value and will restart when the input voltage rises above the restart value. These values are configurable via the VictronConnect app.
