Description
xOrion-Tr 48/48-6A (280W) Isolated DC-DC Converter
The Victron Orion-Tr 48/48-6A is a galvanically isolated DC-DC converter rated at 280W, designed for 48V to 48V applications where electrical isolation between input and output is required. It suits professional installations in vehicles, vessels, off-grid systems and industrial equipment where ground loop issues or safety separation are a concern.
Key Features
- Galvanic isolation between input and output eliminates ground loop interference and improves safety in dual-battery or mixed-system installations.
- 280W continuous output power at 6A on a 48V output, suitable for powering 48V loads or charging a secondary 48V battery bank.
- Wide input voltage range accommodates fluctuating 48V bus voltages typical of solar, battery and alternator sources.
- Compact, enclosed aluminium housing with a weight of 1.3 kg, suitable for panel or DIN-rail adjacent mounting in confined spaces.
- Output voltage is adjustable via an internal potentiometer, allowing fine-tuning to match specific battery or load requirements.
- High conversion efficiency reduces heat generation and minimises energy losses in DC distribution systems.
Product Overview
The Orion-Tr range uses a transformer-based topology to provide true galvanic isolation, meaning the input and output circuits share no direct electrical connection. This is particularly important in marine and vehicle installations where chassis grounds differ between systems, and in any application where fault current paths need to be controlled. The 48V-in to 48V-out configuration is not a simple pass-through: the converter actively regulates the output voltage, which can be set independently of the input.
At 280W and 6A output, this unit is well suited to supplying 48V DC loads or maintaining a secondary 48V battery in systems where the primary and secondary banks must remain isolated. The adjustable output voltage means it can be configured to deliver a float or absorption-level voltage to a secondary battery without requiring an additional charge controller. Installers working on dual-bank lithium or lead-acid systems will find this flexibility useful in practice.

Installation Notes
Installation should be carried out by a qualified electrician or experienced system integrator familiar with DC power systems. Ensure input and output wiring is correctly rated for the current and voltage involved. In marine applications, follow applicable NMEA or ISO wiring standards. For vehicle installations, verify that the converter mounting location is protected from moisture and excessive heat. The output voltage adjustment potentiometer should only be set with the unit powered down unless the installer is confident working on live low-voltage DC circuits.
