Victron Energy Orion-Tr Smart 48/24-16A (380W) Isolated DC-DC charger - ORI482438120

The Victron Energy Orion-Tr Smart 48/24-16A (380W) Isolated DC-DC Charger, manufacturer part number ORI482438120, is a Bluetooth-enabled battery charger designed to charge nominal 24V auxiliary and service batteries from a compatible 48V DC power source. Combining galvanic isolation, intelligent battery charging, programmable operating settings, and integrated electrical protection, this charger is an excellent solution for off-grid energy systems, marine applications, industrial equipment, specialty vehicles, and other installations requiring controlled charging between different DC voltage systems.

Engineered for 48V-to-24V DC power conversion, the Orion-Tr Smart provides a continuous output current of 16A at its rated operating conditions. Its intelligent charging system supports adaptive three-stage charging and configurable battery charging parameters, allowing installers to optimize charging performance for compatible lead-acid and lithium battery systems.

Important: The ORI482438120 is a 48V-to-24V isolated DC-DC battery charger. It is not a DC-to-AC inverter, AC battery charger, or solar MPPT charge controller. Battery charging parameters must be configured according to the connected battery manufacturer's specifications.
