Victron Orion-Tr Smart 48/12-30A DC-DC Charging Booster 360W, Isolated

The Orion-Tr Smart 48/12-30A from Victron (MPN: ORI481236120) is an isolated DC-DC charge booster designed for the controlled charging of a 12 V service battery from a 48 V system. It delivers 30 A of charging current, uses an adaptive three-stage charging method, and can be configured via Bluetooth using the VictronConnect app. Galvanic isolation electrically separates the input, output, and housing from one another.

Controlled Charging from 48 V Systems

• Electrical isolation with 200 VDC between the input, output, and housing
• Adaptive three-stage charging algorithm for lead-acid and lithium batteries
• Configuration and monitoring via Bluetooth and VictronConnect
• Integrated motor shutdown detection
• Charger and power supply modes
• Remote on/off control
• Multiple units can be connected in parallel
• Over-temperature, overload, and short-circuit protection

Adaptive charging method for lead-acid and lithium batteries

In charger mode, it operates with three charging stages: constant current, constant voltage, and trickle charge. The duration of the constant-voltage phase can be adaptively adjusted based on the previous charging history. Eight preconfigured battery profiles are available for various lead-acid and lithium batteries. Additionally, the charging parameters can be set to match the battery manufacturer’s specifications.

Bluetooth Configuration with VictronConnect

Operating data, alerts, and device statuses can be accessed via the VictronConnect app using the built-in Bluetooth interface. The charging profile, input and output voltage, input voltage lockout, and engine shutdown detection can also be configured. The app does not display input or output current for this model. A VE.Direct connection is not available.

Engine Shutdown Detection and Remote Control

In charger mode, the Orion-Tr Smart can detect whether the engine or alternator is active. If the engine is turned off, the charging process stops and the input battery is disconnected from the 12 V output system. Additionally, the unit can be turned on and off via the remote connection using a switch, relay contact, or suitable control signal.

Installation and Connection Instructions

The unit must be mounted vertically on a non-flammable surface with the power terminals facing downward. At least 10 cm of clearance is required above and below the unit for cooling. Avoid mounting the unit directly above a battery. The charge booster is not protected against reverse polarity. Therefore, the input and output polarity must be carefully checked before connection. The installation requires external battery fuses and copper cables sized appropriately for the cable length.
