Description
xVictron Orion-Tr 24/12-20 (240W) Non-Isolated DC-DC Converter
The Victron Orion-Tr 24/12-20 is a non-isolated DC-DC converter that steps a 24V supply down to a 12V output at up to 20A (240W). It is designed for mobile, marine and off-grid applications where two different DC voltage rails need to run from a single battery bank, or where a 12V load must be powered from a 24V system.
Key Features
- Input voltage: 24V nominal, with a wide input range suitable for real-world battery systems.
- Output voltage: 12V at up to 20A continuous, giving a maximum output power of 240W.
- Non-isolated design: shares a common ground between input and output, which simplifies wiring in vehicle and marine installations where a shared chassis ground is already present.
- Compact and lightweight at 0.26kg, making it straightforward to mount in tight enclosures or behind panels.
- Retail packaging: supplied in Victron retail box, suitable for resale or end-user installation.
- Fixed output voltage: delivers a stable 12V output regardless of fluctuations on the 24V input side, protecting connected 12V equipment.
Product Overview
The Orion-Tr range uses a switching converter topology to step voltages down efficiently, avoiding the heat and energy waste associated with linear regulators. The non-isolated variant is the appropriate choice when the input and output share a common negative (ground), which is standard in most vehicle, caravan and boat installations. If galvanic isolation between the two voltage rails is required, the isolated version of the Orion-Tr should be selected instead.
At 240W output, this unit is well suited to powering 12V accessories, lighting circuits, control electronics or communication equipment from a 24V house bank. The fixed 12V output means no adjustment is needed during commissioning, and the converter will maintain a stable output as the 24V battery discharges through its normal operating range.
Victron's Orion-Tr converters are widely used alongside MultiPlus and Quattro inverter-chargers, SmartSolar MPPT controllers and Lynx distribution systems in larger 24V off-grid and marine installations that also need a 12V rail for ancillary loads.

Installation Notes
The Orion-Tr 24/12-20 is a non-isolated converter and shares a common ground between input and output. Confirm that your installation does not require galvanic isolation before selecting this unit. Wiring should be sized appropriately for the input current draw at 24V and the 20A output. Fuse both the input and output cables as close to the battery or busbar as practical. Installation in vehicles, vessels or off-grid systems should be carried out by a competent electrician or qualified installer familiar with DC systems.
