The Victron Orion-Tr 24/24-5A is a galvanically isolated DC-DC converter that takes a 24V input and produces a regulated 24V output at up to 5A, delivering 120W continuous. Galvanic isolation keeps the input and output circuits electrically separate, so it suits vehicle, marine and off-grid installations where two 24V systems need to stay independent.

Victron dc dc converter with galvanic isolation

• Isolation, galvanic separation between input and output, removing ground loop interference between two DC systems.
• Output, 24V nominal output at up to 5A continuous, giving 120W of isolated DC power.
• Input, 24V nominal input, with the wide voltage range typical of the Orion-Tr series to handle fluctuations from vehicle or battery systems.
• Housing, compact, enclosed casing for confined spaces such as vehicle cabinets, battery compartments and marine panels.
• Weight, 0.5 kg.
• Packaging, supplied retail packed, GTIN 8719076016892.

Applications

Isolation matters wherever a chassis or common ground could otherwise let current flow between two separate battery systems. The 24/24-5A variant is useful where source and load are both nominally 24V but must stay isolated: charging a service battery from a starter battery on a 24V truck or coach, or running 24V instrumentation from a main bank without introducing ground-referenced noise. It also suits dual-battery setups in commercial vehicles and coaches, isolated DC distribution on boats, and secondary battery charging in caravans and motorhomes with 24V systems.

Installation notes

Fit this as part of a professional or experienced installation. Wiring on both input and output should be correctly rated for the current, with fusing on each side. Check that the source battery's voltage, including engine-on charging voltage, sits within the unit's input range before wiring it in. Marine installations should follow the wiring standards applicable to the vessel.
