Description
Power your service battery with confidence using the Victron Orion-TR Smart 12/12-18A (220W) Isolated DC-DC Charger or Power Supply. This versatile unit operates as both a DC-DC battery charger and a precise constant voltage power source, delivering reliable charging across a wide input and output range. Designed to handle Euro 5 and Euro 6 smart alternators, it mitigates low charging voltage and voltage drop over long cable runs in boats and RVs, ensuring your starter battery stays protected while the house battery charges fully.
Smart, flexible charging for any journey
- Isolated DC-DC charger or power supply with a wide input/output range for versatile vehicle, boat, and RV use.
- Bluetooth Smart Enabled — monitor, configure, and update the charger from any Bluetooth-enabled device using the VictronConnect app.
- Instant Readout — key data, warnings, and alarms appear on the device list in VictronConnect without needing to connect physically.
- Fully programmable or fixed output — choose a configurable battery charge algorithm or a fixed output voltage to suit your battery chemistry.
- Smart Alternator Compatibility — engine running detection ensures the unit only charges when appropriate, protecting the starter battery.
- Adaptive 3-Stage Charge Algorithm — Bulk, Absorption, and Float to optimize charging for both lead-acid and lithium batteries.
- Lead-acid optimization — absorption time adapts during shallow discharges to prevent overcharging; after deep discharge, absorption time increases to fully recharge.
- Lithium support — fixed absorption time with a default 2-hour setting for lithium batteries.
- Remote On/Off — connect a remote switch or relay to control the unit, or switch via the H terminal (battery +) or L terminal (battery −) as needed.
- Paralleling capability — all models are short-circuit proof and can be paralleled to increase total output current with no practical limits on the number of units.
- Protection and durability — high-temperature protection reduces output current at elevated ambient temperatures; IP43 protection when installed with downward-facing screw terminals.
- Easy installation — screw terminals and no special tools required; built-in input fuse (not replaceable) for safety.
- Remote shutdown safeguard — engine shutdown detection stops the converter when the engine isn’t running, preventing unwanted starter battery discharge.
