It uses an adaptive 3-stage charge profile with bulk, absorption, and float stages, and it can also work as a fixed-output power supply when the installation calls for regulated DC power rather than battery charging.\u003c\/p\u003e\u003cp\u003eFor boat installations, the isolated layout is useful when the input and output sides should keep separate chassis grounds. The 48V input models accept a 32 to 70 VDC input range, support lead-acid and lithium batteries, and operate from -20 C to +55 C with output derating above 40 C.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003e48V input family with output options for 12V at 30A, 24V at 16A, or 48V at 8A.\u003c\/li\u003e\n\u003cli\u003eBuilt-in Bluetooth allows monitoring and setup through VictronConnect without opening the installation area after commissioning.\u003c\/li\u003e\n\u003cli\u003eAdaptive 3-stage charging supports lead-acid and lithium battery charging, with configurable settings for the battery bank.\u003c\/li\u003e\n\u003cli\u003eGalvanic isolation is rated at 200V DC between input, output, and case, which helps keep separate DC systems apart.\u003c\/li\u003e\n\u003cli\u003eRemote on\/off and engine running detection help manage charging in systems where charging should stop when the engine or source is not available.\u003c\/li\u003e\n\u003cli\u003eCan be used as a DC power supply, with output voltage set by Bluetooth.\u003c\/li\u003e\n\u003cli\u003eIP43 rating applies to the electronic components and IP22 to the connection area when mounted with screw terminals facing downward.\u003c\/li\u003e\n\u003cli\u003eScrew terminals accept cable up to 16 mm2 \/ AWG 6, giving room for correctly sized marine DC cabling.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eVariants\u003c\/h6\u003e\u003cp\u003eThe variants below all belong to the 48V input Orion-Tr Smart isolated charger range.\u003c\/p\u003e\u003cp\u003eOutput voltage and output current are the key differences. The 32 to 70 VDC input range, Bluetooth setup, galvanic isolation, screw-terminal DC connection, and IP43\/IP22 protection rating remain consistent across these three 48V input models.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eORI481238120: 12V output with 30A output current. This configuration fits a 48V source system feeding a 12V service battery or 12V DC loads through an isolated charger.\u003c\/li\u003e\n\u003cli\u003eORI482438120: 24V output with 16A output current. This configuration fits a 48V source system feeding a 24V service bank or 24V DC distribution through isolated conversion.\u003c\/li\u003e\n\u003cli\u003eORI484838120: 48V output with 8A output current. This configuration keeps the output side at 48V while adding charger control and isolation between source and output circuits.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eInstallation and fit\u003c\/h6\u003e\u003cp\u003eInstall the charger in a dry, ventilated electrical space such as a DC panel area, machinery space, or protected locker. The protection rating is not for exposed deck mounting, and the screw terminals should face downward to match the stated protection category.\u003c\/p\u003e\u003cp\u003eThe 48V input models in this range measure 130 x 186 x 70 mm and weigh about 1.6 kg. Leave space for cable bends, terminal access, and airflow, especially in engine room or lazarette installations where temperature can climb.\u003c\/p\u003e\u003ch6\u003eElectrical and system integration\u003c\/h6\u003e\u003cp\u003eUse it between a 48V source side and the selected output battery or DC distribution side, then configure the charging profile over Bluetooth. The remote on\/off input allows a low-current switch or relay contact to control the charger, so the main DC feed does not need a high-current switch just to enable or disable charging.\u003c\/p\u003e\u003cp\u003eThe engine running detection is useful where charging should depend on source availability. In lithium systems, controlled DC-DC charging also helps avoid direct source loading that can occur when a low-impedance battery is connected without charge control.\u003c\/p\u003e\u003ch6\u003eUse cases on board\u003c\/h6\u003e\u003cp\u003eThis charger is a practical match for boats with a 48V battery system that also needs a separate 12V, 24V, or 48V battery circuit. It makes sense for refits where mixed-voltage equipment remains on board and the installer wants charging control, Bluetooth setup, and isolation instead of a simple converter.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"12V \/ 30A","offer_id":52581993873589,"sku":"QBP531067-V1","price":276.84,"currency_code":"USD","in_stock":true},{"title":"24V \/ 16A","offer_id":52581993906357,"sku":"QBP531067-V2","price":276.84,"currency_code":"USD","in_stock":true},{"title":"48V \/ 8A","offer_id":52581993939125,"sku":"QBP531067-V3","price":276.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1336339_qbp531067.webp?v=1780202224","url":"https:\/\/www.qualityboatparts.com\/products\/qbp531067","provider":"Quality Boat Parts","version":"1.0","type":"link"}
