Description
xVictron Orion-Tr 24/24-17A (400W) Isolated DC-DC Converter
The Victron Orion-Tr 24/24-17A is a galvanically isolated DC-DC converter rated at 400W, designed for 24V to 24V applications where electrical isolation between source and load is required. It is suited to professional vehicle, marine, off-grid and industrial installations where two separate 24V systems must be kept electrically independent.
Key Features
- Galvanic isolation between input and output, preventing ground loops and protecting sensitive electronics from voltage spikes on the source circuit.
- 400W continuous output power at 17A on a 24V output, providing a stable regulated supply for secondary battery banks or loads.
- Wide input voltage range typical of the Orion-Tr series, accommodating fluctuating alternator or battery voltages without shutting down.
- Compact, aluminium enclosure with a weight of 1.52 kg, suitable for installation in confined spaces on vehicles or vessels.
- Output voltage is adjustable, allowing the converter to be set for the correct charge voltage of the secondary battery chemistry.
- Designed for parallel operation, enabling higher output currents where the application demands more than a single unit can supply.
Product Overview
The Orion-Tr range uses a transformer-based topology to provide true galvanic isolation between the input and output circuits. This is a practical requirement in dual-battery vehicle installations, where the chassis ground of a secondary system (such as a habitation or auxiliary bank) must not be directly connected to the starter battery circuit. It is equally important on boats, where stray current corrosion is a genuine risk if battery systems share a common ground path.
At 400W and 17A output, this unit is capable of charging a 24V auxiliary battery bank from a 24V house or vehicle supply at a meaningful rate. The adjustable output voltage means it can be configured to suit flooded, AGM or lithium battery chemistries, provided the correct voltage is set during commissioning. It does not include a Bluetooth interface or load output control; for those features, the Orion-Tr Smart range should be considered instead.
The converter can be operated in parallel with additional Orion-Tr units of the same model to increase total output current. This is a straightforward way to scale capacity without replacing the unit, and is a common approach in larger vehicle or marine builds where space for a single larger converter is limited.

Installation Notes
Installation should be carried out by a qualified electrician or experienced system integrator familiar with DC power systems. Correct fusing of both the input and output cables is essential. On marine installations, wiring must comply with the relevant standards for recreational craft or commercial vessels. The output voltage should be set to match the target battery chemistry before the unit is put into service. Ensure adequate ventilation around the unit during operation.
