About this product
Victron Orion-Tr Smart 12/12 18 A (220W) Isolated DC-DC provides controlled DC-to-DC charging between a starter-battery supply and a service battery.
Adaptive charging and engine-running detection help charge the service battery from a compatible alternator system while protecting the starter supply. Bluetooth supports setup and monitoring, and the unit can also be configured as a fixed-voltage power supply.
Key features
- Nominal model combination: 12 V input / 12 V output
- Bluetooth configuration and monitoring with VictronConnect
- Adaptive battery charging or power-supply operation
- Engine-running detection and remote on/off control
- Isolated version: input and output are galvanically separated.
Match the input/output voltages and battery profile. Isolated and non-isolated versions have different grounding requirements; follow this model's wiring diagram.
