Victron Orion-Tr Smart 12/12-18A Isolated DC-DC Charger 220W | ORI121222120

The Victron Orion-Tr Smart 12/12-18A is a galvanically isolated DC-DC charger for vehicle, marine and off-grid systems where a secondary battery is charged from a 12V source. It supplies up to 18A, or 220W, of charge current and is configured over Bluetooth rather than physical switches.

Key features of the Orion-Tr Smart 12/12-18A isolated DC-DC charger

• Isolation, full galvanic separation between input and output circuits.
• Output, 18A maximum current, up to 220W continuous charge power at 12V.
• Bluetooth, built in, configured and monitored through the VictronConnect app on iOS and Android.
• Charge profile, adaptive 3-stage bulk, absorption and float algorithm for lead-acid and lithium chemistries.
• Engine detection, starts charging based on an input voltage threshold, protecting the starter battery when the engine is off.
• Weight, 1.3 kg in a sealed housing suited to engine bays and lockers.

Applications

This charger suits dual-battery setups in campervans, motorhomes and caravans, where a leisure battery draws charge from the alternator. It is equally at home in marine installations that need isolation between the start battery and the service bank, and in off-grid or expedition vehicles running lithium leisure batteries that need a correct multi-stage profile. It also works in truck auxiliary power systems and alongside a solar charge controller as a supplementary DC-DC charger.

Configuration and monitoring

Charge voltages, absorption time, tail current and the engine detection threshold are all set in VictronConnect, with no DIP switches involved. The unit can also join VE.Smart Networking, taking battery temperature and voltage readings from a connected BMV monitor or Smart Battery Sense for a more accurate charge.
