It suits boats that need controlled charging from a 48 V battery bank or charging source to a 12 V service battery, electronics battery, or auxiliary DC circuit.\u003c\/p\u003e\u003cp\u003eThis Orion-Tr Smart model uses an adaptive 3-stage charging profile with bulk, absorption, and float stages, and it can also run as a fixed-voltage power supply when set up that way. Built-in Bluetooth allows setup and monitoring through VictronConnect, which is useful when the charger is mounted inside a console, technical locker, or machinery space where direct access is limited.\u003c\/p\u003e\u003cp\u003eThe isolated design keeps input, output, and case separated by 200 VDC galvanic isolation, which is helpful on vessels where 48 V and 12 V systems need to remain electrically separated. The output voltage is adjustable from 10-15 V, and the unit can be paralleled with additional units when a higher total output current is needed.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eConverts a 32-70 VDC input to a 12.2 V nominal output for 48 V to 12 V onboard power systems.\u003c\/li\u003e\n\u003cli\u003eDelivers 20 A continuous output at 40 °C, with 240 W continuous output at that temperature.\u003c\/li\u003e\n\u003cli\u003eAdaptive 3-stage charging supports lead acid and lithium battery charging when configured for the battery type.\u003c\/li\u003e\n\u003cli\u003eBluetooth setup and monitoring through VictronConnect allows charging parameters, live data, warnings, and alarms to be checked from a phone or tablet.\u003c\/li\u003e\n\u003cli\u003eCan be configured as a battery charger or as a fixed-voltage DC power supply.\u003c\/li\u003e\n\u003cli\u003eRemote on\/off connection allows control from a low-current switch, relay contact, or engine-run signal.\u003c\/li\u003e\n\u003cli\u003eEngine shutdown detection helps prevent unwanted discharge of the input battery when the charging source is not active.\u003c\/li\u003e\n\u003cli\u003eIP43 protection applies to the electronic components when the unit is mounted with the screw terminals facing downward.\u003c\/li\u003e\n\u003cli\u003eScrew terminals accept cable up to 16 mm2, or AWG 6, without requiring special installation tools.\u003c\/li\u003e\n\u003cli\u003eShort-circuit protection, high-temperature derating, and parallel operation support practical installation in demanding DC systems.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eElectrical and system integration\u003c\/h6\u003e\u003cp\u003eThis charger is a strong match for vessels using a 48 V house bank, propulsion support bank, or other 48 V DC source while still carrying 12 V loads such as electronics, lighting, pumps, instruments, or a smaller auxiliary battery. It gives those 12 V circuits a controlled supply instead of relying on an unregulated step-down connection.\u003c\/p\u003e\u003cp\u003eThe adjustable 10-15 V output range gives the installer room to match the required charging profile or supply voltage. For battery charging, the correct battery type and charge settings should be configured in VictronConnect before the system is put into service.\u003c\/p\u003e\u003ch6\u003eInstallation and fit\u003c\/h6\u003e\u003cp\u003eThe enclosure measures 130 x 186 x 70 mm and weighs about 1.3 kg, so it can fit in many electrical lockers, helm spaces, or protected technical areas. It should be mounted where airflow is available and where the terminal orientation supports the stated IP protection.\u003c\/p\u003e\u003cp\u003eThe operating temperature range is -20 °C to +55 °C, with output derating above 40 °C. In an engine room or other warm compartment, cable sizing, fuse placement, ventilation, and access for inspection should be planned carefully as part of the DC installation.\u003c\/p\u003e\u003ch6\u003eUse cases on board\u003c\/h6\u003e\u003cp\u003eOn a cruising boat, workboat, or fishing vessel with mixed-voltage DC architecture, this charger helps bridge a 48 V source and 12 V equipment without tying the grounds together. It is useful for owners and installers who need a controlled 12 V charging or supply point while keeping the electrical layout clean and serviceable.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":52581877383349,"sku":"QBP084116","price":159.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1332378_qbp084116.jpg?v=1780201065","url":"https:\/\/www.qualityboatparts.com\/products\/qbp084116","provider":"Quality Boat Parts","version":"1.0","type":"link"}
