Izolační nabíječ Orion Tr Smart 24/24-12A (280W) DC-DC

The Victron Energy Orion Tr Smart 24/24-12A (280W) isolated DC-DC charger is a professional converter and charger designed for dual-battery systems on board. It recharges a service battery from an alternator or a starter battery, or operates as a fixed-voltage power supply. It provides 200V DC galvanic isolation between the input, output, and case.

This charger provides continuous power of 280W at 40°C (320W at 25°C) and a continuous output current of 12A at 40°C. Its efficiency reaches 89%. It can operate within a temperature range of -20 to +55°C.

The Orion Tr Smart 24/24-12A charger has an input voltage range of 16-35V and an adjustable output voltage of 20-30V, with a nominal voltage of 24.2V.

Yes, the charger includes multiple electronic protections, including against high temperatures, overcharging, short circuits, and overheated connectors.

The integrated Bluetooth Smart allows monitoring, configuration, and software updates of the charger via the VictronConnect application, available on smartphone or tablet.

The charger uses a 3-stage adaptive charging algorithm: bulk (fast charge), absorption (constant voltage with adjusted duration) and float (float charge). The absorption time is automatically adjusted for lead-acid batteries and is set to 2 hours by default for lithium batteries.

Yes, in power mode, the output voltage remains stable, regardless of the load applied or variations in the input voltage (within the specified range).

The engine-running detection function allows the charger to supply power only when the vehicle's engine is running. This prevents the starter battery from discharging when the alternator is not providing current and does not require any modification to the vehicle's system.

The charger is rated IP43 when installed with the screw terminals oriented downward. This means it is protected against solid objects larger than 1 mm and against water splashes.

Yes, the Orion Tr Smart 24/24-12A charger provides 200V DC galvanic isolation between the input, output, and case, improving the electrical safety of the system.

The charger must be mounted vertically on a non-flammable surface, with the power terminals facing downward. It is important to leave a minimum clearance of 10 cm above and below the product for optimal cooling.

Never mount the charger directly above the battery to prevent damage from battery gases. It must be installed near the battery, but not directly on top of it.

For battery connections, use flexible multi-strand copper cables. The diameter of individual strands must not exceed 0.4 mm or 0.125 mm² (AWG26). A fuse must be included in the installation according to the product manual's recommendations.

The manual recommends a 16mm² cable with at least 122 strands (class 5 or higher per VDE 0295, IEC 60228, and BS6360), such as a "Tri-rated" class 5 cable. Using strands that are too thick can result in high contact resistance and overheating.

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

The charger can be turned on or off remotely via the remote on/off connector or via the VictronConnect app. This allows use cases such as a hardwired switch or automatic control by a battery management system (BMS).

Yes, the Orion Tr Smart charger is compatible with smart alternators (ECU-controlled) that provide a variable output voltage and can shut down when not required. It includes an engine-running detection mechanism to prevent the starter battery from discharging.

Yes, the charger is compatible with lithium batteries. Its 3-stage adaptive charging algorithm adjusts the absorption time, which is set to 2 hours by default for lithium batteries.

Yes, the charger has a programmable charging algorithm and eight pre-programmed battery settings, configurable via the VictronConnect app to adapt to different battery types.

Yes, the Orion-Tr Smart DC-DC Charger is designed to isolate the starter battery from the service battery when the engine is not running, ensuring the starter battery is not discharged.
