Victron Energy ORI482428110 280W 48/24-12A Orion-Tr DC-DC Converter
Victron Energy Orion-Tr 48/24-12A 280W Isolated DC-DC Converter
Convert, charge, and protect reliable isolated DC power wherever the job takes you.
The Victron Energy Orion-Tr 48/24-12A (ORI482428110) is a professional-grade isolated DC-DC converter engineered for demanding off-grid, marine, automotive, and industrial applications. Designed as a true worldwide product, it steps a 48V input down to an adjustable 24V output and can double as a battery charger when you need to top up a secondary battery bank in a mixed-voltage system.
Rated at 280W continuous at 40°C and 320W at 25°C, this unit is built to work hard in the heat and dust that Australian conditions routinely dish out. With galvanic isolation between input, output, and case, it's the right choice anywhere electrical noise or ground-loop interference could cause problems from ute-based dual-battery setups and solar storage systems to commercial vehicles and marine electrics.
Key Specifications

- Short circuit output current: 30A
- Continuous output power at 40°C: 280W
- Continuous output power at 25°C: 320W
- Efficiency: 89%
- Galvanic isolation: 200V DC between input, output, and case
- Output voltage tolerance: ±0.2V
- Output noise: 2mV rms
- Off-load current draw: less than 80mA
- Operating temperature: −20°C to +55°C (derate 3% per °C above 40°C)
- IP43 protection rating (terminals oriented downwards)
- DC connection: Screw terminals, max cable cross-section 6mm² (AWG10)
Features & Benefits
- Remote on/off input: Eliminate the need for a heavy-duty high-current switch in your input wiring. Connect a simple low-power toggle or wire directly to an engine run/stop signal for clean, hands-free control in vehicle and marine installs.
- Adjustable output voltage (20–30V): Fine-tune the output to match the exact needs of your load or charging target. Use it to float or bulk-charge a 24V battery bank, or dial it in precisely for sensitive electronics no guesswork, no overvoltage risk.
- Doubles as a battery charger: In mixed-voltage systems (e.g., a 48V bus with a 24V accessory battery), the Orion-Tr handles charging duties directly, reducing the need for a separate charger and simplifying your system design.
- Galvanic isolation (200V DC): Complete electrical separation between input, output, and chassis eliminates ground loops, suppresses noise, and protects sensitive loads essential on boats, caravans with solar, and commercial vehicles sharing chassis grounds.
- Parallel operation unlimited units: Stack as many units as your system demands. No current-sharing modules, no complex wiring; just connect in parallel and let the Orion-Tr units share the load automatically.
- Short circuit proof: Internal protection means a fault on the output won't destroy the unit. It recovers cleanly once the fault is cleared reducing costly downtime in the field.
- High temperature derating (not shutdown): Rather than cutting out abruptly, the Orion-Tr reduces output current gracefully as temperature climbs. In a hot Australian engine bay or a sun-baked 4WD, that means the system keeps working just at a reduced rate rather than leaving you stranded.
- IP43 rated: Splash and dust resistance when installed with terminals facing down. Suitable for under-bonnet, underbody, and exposed marine locations where a plain PCB-in-a-box wouldn't survive.
- Screw terminals no special tools: 6mm² (AWG10) cable capacity on standard screw terminals. Fast, solid, field-serviceable connections without crimping tools or proprietary connectors.
- Input fuse protection: Fused on 12V and 24V input models for added circuit protection. Note: the ORI482428110 (48V input) should be fused externally per Victron installation guidelines.

Frequently Asked Questions
Can this unit charge a 24V battery as well as power 24V loads?
Yes. The adjustable output (20–30V) means you can set it to a charge voltage appropriate for your 24V battery chemistry. It works as both a DC load supply and a battery charger within the same installation.
Does the Orion-Tr 48/24-12A provide galvanic isolation?
Yes. There is 200V DC galvanic isolation between the input, output, and case. This makes it suitable for marine and solar applications where ground loops and electrical noise are a concern.
Can I run multiple units in parallel to get more current?
Yes. Victron specifies that an unlimited number of Orion-Tr units can be connected in parallel. Simply wire them in parallel on both input and output sides no additional load-sharing hardware is needed.
What happens if the output is short-circuited?
The unit is short circuit proof and will recover automatically once the fault is cleared. It will not be permanently damaged by an output short, reducing the risk of costly field failures.
Is this unit suitable for under-bonnet or outdoor installation in Australian conditions?
It carries an IP43 rating when installed with screw terminals oriented downwards, offering protection against dust and splashing water. It operates across −20°C to +55°C, with output derating above 40°C rather than abrupt shutdown making it well suited to hot Australian environments.
