Victron Energy ORI121236120 Orion-Tr Smart 12/12-Volt 30A 360W Isolated DC-DC Charger with Bluetooth

The Victron Energy Orion-Tr Smart 12/12-30A (360W) Isolated DC-DC Charger (ORI121236120) is a professional-grade, adaptive 3-stage DC-to-DC battery charger with built-in Bluetooth connectivity. Engineered for dual battery systems in vehicles, boats, and RVs, it charges a service (house) battery from the starter battery and alternator—even when a Euro 5 or Euro 6 smart alternator supplies insufficient voltage or when long cable runs cause voltage drops.

Complete galvanic isolation protects against ground loops and electrical noise, making this charger especially well-suited for marine fiberglass hulls and complex vehicle electrical systems. It can also be configured as a fixed-voltage DC power supply when a constant output is needed.

Key Features:

• Adaptive 3-Stage Charging: Bulk, absorption, and float charging stages; automatically extends absorption time after deep discharges
• Galvanic Isolation: Fully isolated input and output eliminate ground loop interference and protect alternator electronics
• Smart Alternator Compatible: Built-in engine-running detection ensures compatibility with modern Euro 5/Euro 6 smart alternators
• Bluetooth via VictronConnect App: Monitor status, adjust settings, view warnings and alarms, and update firmware wirelessly from any smartphone or tablet
• Remote On/Off: Two-pole connector accepts a remote switch or relay contact for convenient system integration
• Dual-Mode Operation: Configurable as a 3-stage battery charger or fixed-output DC power supply
• Eight Pre-Programmed Battery Profiles: Supports lead-acid (flooded, AGM, gel) and lithium battery chemistries with a fully programmable custom profile option
• Expandable: Multiple units can be connected in parallel to increase output current capacity
• IP43 Rated: Protected against water spray when installed with screw terminals oriented downward
• Short-Circuit Proof: Built-in protection safeguards the unit and connected components
