The Victron Orion-Tr Smart Isolated 48/12-30A DC-DC Charger is a professional-grade battery charger and power supply designed to efficiently convert 48V DC input to a regulated 12V output. Delivering up to 30A (360W), it is ideal for charging 12V auxiliary batteries from 48V electrical systems found in electric vehicles, industrial equipment, commercial vehicles and specialised mobile power applications.
Featuring fully isolated input and output circuitry, the Orion-Tr Smart provides enhanced electrical protection and system flexibility, making it suitable for demanding installations where galvanic isolation is required. Victron's adaptive three-stage charging algorithm (Bulk, Absorption and Float) optimises battery charging for lead-acid batteries, while configurable settings also allow charging of lithium batteries or operation as a regulated DC power supply.
Integrated Bluetooth Smart technology allows complete configuration, monitoring and firmware updates using the free VictronConnect app. Installers can adjust charging voltages, monitor performance, receive diagnostic information and customise operating parameters directly from a smartphone or tablet without additional hardware.
The Orion-Tr Smart also includes intelligent engine running detection, eliminating the need to connect an ignition signal in many vehicle applications. Built-in protection against overheating, IP43 protection (when mounted with terminals facing down) and the ability to parallel multiple units make it an excellent solution for professional vehicle, marine and industrial electrical systems.
