It is designed for professional installations where a secondary 12V battery needs to be charged from a 48V house bank, traction battery or DC bus, without an electrical connection between the two circuits. Built-in Bluetooth allows configuration and monitoring via the VictronConnect app without additional hardware.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eGalvanic isolation between input and output eliminates ground loop issues and protects both battery banks from cross-contamination of faults.\u003c\/li\u003e\n  \u003cli\u003e48V input to 12V output conversion at 30A continuous, delivering up to 360W of charging power.\u003c\/li\u003e\n  \u003cli\u003eIntegrated Bluetooth with VictronConnect app support for configuration, monitoring and firmware updates from a smartphone or tablet.\u003c\/li\u003e\n  \u003cli\u003eAdaptive 3-stage charging algorithm (bulk, absorption, float) ensures correct charge management for the secondary battery.\u003c\/li\u003e\n  \u003cli\u003eWide input voltage range accommodates real-world 48V systems, including those with variable bus voltage under load.\u003c\/li\u003e\n  \u003cli\u003eEngine detection input allows the unit to activate only when the alternator or engine is running, protecting the source battery from discharge.\u003c\/li\u003e\n  \u003cli\u003eCompact, wall-mountable aluminium enclosure rated for permanent installation in vehicles, vessels and fixed off-grid systems.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eProduct Overview\u003c\/h3\u003e\n\u003cp\u003eThe Orion-Tr Smart range differs from basic DC-DC converters by incorporating a proper multi-stage battery charging profile rather than simply regulating output voltage. This matters in practice because a flat secondary battery will draw maximum current until it reaches absorption voltage, then taper off correctly, rather than being held at a fixed voltage that either undercharges or stresses the battery. The result is longer battery life and a fully charged auxiliary bank.\u003c\/p\u003e\n\n\u003cp\u003eGalvanic isolation is a key specification for many installations. On boats, it prevents stray current corrosion between separate battery systems. In vehicles with dual battery setups, it avoids chassis ground conflicts. In 48V off-grid or telecom systems feeding 12V auxiliary loads, it provides a clean separation that simplifies fault-finding and meets installation best practice. The transformer-based isolation in the Orion-Tr Smart is not a software feature; it is a physical barrier built into the converter topology.\u003c\/p\u003e\n\n\u003cp\u003eVictronConnect Bluetooth is built in as standard. There is no need for a separate interface dongle or wired connection to set charge voltages, absorption time, or engine detection behaviour. The unit can also be integrated into a wider Victron system via a VE.Direct connection, allowing data to be logged through a GX device or the VRM portal.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSKU: ORI481238120\u003c\/li\u003e\n  \u003cli\u003eInput voltage: 48V nominal\u003c\/li\u003e\n  \u003cli\u003eOutput voltage: 12V (adjustable)\u003c\/li\u003e\n  \u003cli\u003eOutput current: 30A continuous\u003c\/li\u003e\n  \u003cli\u003eOutput power: 360W\u003c\/li\u003e\n  \u003cli\u003eIsolation: Galvanic (transformer-based)\u003c\/li\u003e\n  \u003cli\u003eCommunication: Bluetooth (VictronConnect), VE.Direct\u003c\/li\u003e\n  \u003cli\u003eWeight: 1.8 kg\u003c\/li\u003e\n  \u003cli\u003eGTIN: 8719076065586\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eCharging a 12V service or auxiliary battery from a 48V lithium house bank in marine or motorhome installations.\u003c\/li\u003e\n  \u003cli\u003eSupplying 12V loads and batteries from a 48V off-grid DC bus in cabins, shelters or remote installations.\u003c\/li\u003e\n  \u003cli\u003ePowering 12V control circuits or auxiliary systems in 48V electric vehicle or golf cart conversions.\u003c\/li\u003e\n  \u003cli\u003eFeeding 12V instrumentation or communications equipment from a 48V telecom or industrial DC supply.\u003c\/li\u003e\n  \u003cli\u003eDual-battery systems where galvanic isolation is required to prevent ground loop interference or stray current corrosion.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eWhat Is Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eOrion-Tr Smart 48\/12-30A isolated DC-DC charger unit\u003c\/li\u003e\n  \u003cli\u003eMounting hardware\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eInstallation Notes\u003c\/h3\u003e\n\u003cp\u003eThis unit should be installed by a qualified electrician or experienced system integrator familiar with DC power systems.
