Victron Energy Orion-Tr Smart DC-DC Charger, 48V/12V, 20A, 240W

Overview

The Victron Energy ORI481224120 is an Orion-Tr Smart 48/12-20A isolated DC-DC charger that takes a 32-70 VDC input and charges or supplies a 12 V system at up to 20 A, with 240 W continuous output at 40 °C. 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.

This 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.

The 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.

Key features

• Converts a 32-70 VDC input to a 12.2 V nominal output for 48 V to 12 V onboard power systems.
• Delivers 20 A continuous output at 40 °C, with 240 W continuous output at that temperature.
• Adaptive 3-stage charging supports lead acid and lithium battery charging when configured for the battery type.
• Bluetooth setup and monitoring through VictronConnect allows charging parameters, live data, warnings, and alarms to be checked from a phone or tablet.
• Can be configured as a battery charger or as a fixed-voltage DC power supply.
• Remote on/off connection allows control from a low-current switch, relay contact, or engine-run signal.
• Engine shutdown detection helps prevent unwanted discharge of the input battery when the charging source is not active.
• IP43 protection applies to the electronic components when the unit is mounted with the screw terminals facing downward.
• Screw terminals accept cable up to 16 mm2, or AWG 6, without requiring special installation tools.
• Short-circuit protection, high-temperature derating, and parallel operation support practical installation in demanding DC systems.

Electrical and system integration

This 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.

The 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.

Installation and fit

The 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.

The 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.

Use cases on board

On 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.

Orders are processed within 2 business days, which includes verification, packing, and dispatch. Orders of $100 or more qualify for free shipping when eligible. For orders under $100, shipping costs are calculated at checkout based on destination, package weight, and selected service. International shipping is available for eligible products, and certain items may require additional handling, warehouse transfers, or may ship directly from the manufacturer, which can affect processing time.

Deliveries are handled by preferred carriers such as USPS, UPS, FedEx, DHL, and others depending on your location and selected service.

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
