DESCRIPTION
Victron 12V to 24V Orion-Tr Smart Isolated DC-DC Charger: Intelligent Power Conversion for Dual-Battery Systems
Efficient 12V to 24V DC-DC Charging with Adaptive 3-Stage Algorithm and Bluetooth Control
The Victron Orion-Tr Smart Isolated DC-DC Charger delivers precise, regulated power conversion from a 12V alternator or battery bank to a 24V auxiliary system. Designed for vehicles, marine vessels, and off-grid installations, this charger solves the common challenge of safely stepping up voltage while maintaining battery health. Unlike basic converters that risk overcharging or undercharging, the Orion-Tr Smart uses an adaptive 3-stage charge algorithm (Bulk, Absorption, Float) to extend battery life and ensure reliable starts every time.
With 15A of continuous current and a peak output of 25A for short surges, it handles demanding loads such as fridge compressors, lighting, and communication equipment. The integrated Bluetooth Smart interface allows full configuration and monitoring via the VictronConnect app, eliminating the need for additional displays or complex wiring. This isolated design provides galvanic isolation up to 200V DC between input, output, and case, protecting sensitive electronics from ground loops and voltage spikes—a critical advantage in mixed-voltage systems.
Smart Alternator Compatibility and Programmable Charge Profiles
Modern vehicles with Euro 5/6 compliant smart alternators often output variable voltage, which can confuse standard DC-DC chargers. The Orion-Tr Smart features an engine detection mechanism that prevents unwanted discharge of the starter battery when the engine is off. You can program custom charge profiles to match your battery chemistry—whether AGM, Gel, Flooded, or Lithium—ensuring optimal charging without manual intervention. The adjustable output voltage range of 20-30V provides flexibility for sensitive loads or specific battery requirements.
Robust Design for Harsh Australian Conditions
Built to withstand the rigours of outback travel and coastal marine environments, the Orion-Tr Smart features an IP43 protection rating when installed with screw terminals facing downward. The extruded aluminium heatsink provides efficient passive cooling, allowing continuous operation at full rated power up to 40°C ambient temperature. Screw terminals accept cables up to 16 mm² (AWG6), ensuring low-resistance connections and minimal voltage drop over long cable runs. The compact footprint of 130 x 186 x 80 mm and weight of 1.8 kg simplifies installation in tight spaces such as under-bonnet, behind panels, or in battery compartments.
