It suits vehicle, marine and off-grid installations where the two DC circuits need to stay electrically separate.\u003c\/p\u003e\u003ch2\u003eKey features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eIsolation\u003c\/strong\u003e, galvanic, transformer-based, keeping input and output circuits electrically separate to prevent ground loops.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput\u003c\/strong\u003e, 24V DC input to 24V DC output (adjustable) at up to 12A, up to 280W.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCooling\u003c\/strong\u003e, convection cooled, no fan.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHousing\u003c\/strong\u003e, enclosed aluminium casing weighing 1.3kg, suited to permanent mounting in confined spaces.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdjustable output\u003c\/strong\u003e, an internal trimmer allows the output voltage to be fine-tuned for different battery types or load requirements.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eProduct overview\u003c\/h2\u003e\u003cp\u003eThe Orion-Tr uses an isolated, transformer-based topology, so the input and output share no common electrical path. That matters in vehicles, vessels and off-grid systems where two battery banks must stay separate for safety, noise rejection or regulatory reasons. Unlike a non-isolated converter, it can charge a secondary battery from a primary bank without creating a ground fault path between them.\u003c\/p\u003e\u003cp\u003eAt 280W and 12A output it can charge a secondary 24V service battery from a 24V starter or house bank, power 24V DC loads from an isolated supply, or feed sensitive electronics with a clean, regulated voltage. It is part of Victron's Orion-Tr series, which covers a range of input and output voltage combinations sharing the same isolated design.\u003c\/p\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCharging a 24V secondary service battery from a 24V starter battery in commercial vehicles or HGVs, with full isolation between banks.\u003c\/li\u003e\n\u003cli\u003eMarine dual-battery systems where galvanic isolation helps prevent corrosion and ground loop interference.\u003c\/li\u003e\n\u003cli\u003eOff-grid and mobile installations needing a regulated, isolated 24V DC supply for control electronics.\u003c\/li\u003e\n\u003cli\u003eMotorhome and coach conversions with separate chassis and habitation battery circuits.\u003c\/li\u003e\n\u003cli\u003eTelecom and industrial DC distribution panels where circuit isolation is a design requirement.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhat's in the box\u003c\/h2\u003e\u003cul\u003e\u003cli\u003e1x Victron Orion-Tr 24\/24-12A (280W) Isolated DC-DC Converter\u003c\/li\u003e\u003c\/ul\u003e\u003ch2\u003eInstallation notes\u003c\/h2\u003e\u003cp\u003eFitting should be done by a qualified electrician or an experienced 12\/24V DC systems installer, with correct cable sizing and fusing on both input and output sides.
