Description
The Victron Orion-TR Smart 12/12-18A (220W) Isolated DC-DC Charger or Power Supply is a compact, versatile solution for boats, RVs, and other vehicles. It functions as both a DC-DC battery charger and a precise constant-voltage power source, delivering reliable charging while protecting the starter battery across a wide input/output range.
- Isolated output: Provides an isolated output that charges the service (house) battery without risking the starter battery, and can operate as either a charger or a fixed voltage power source.
- Bluetooth Smart Enabled: Monitor, configure, and update from any Bluetooth-enabled device using the VictronConnect app; Instant Readout shows key data, warnings, and alarms.
- Engine/Smart Alternator Compatibility: Smart alternator-friendly with engine running detection to ensure charging only when appropriate, protecting the starter battery.
- Adaptive 3-Stage Charge Algorithm: Optimizes charging with Bulk, Absorption, and Float stages for both lead-acid and lithium batteries.
- Lithium support: Lithium batteries are supported with fixed absorption time and a default 2-hour setting for reliable charging.
- Remote On/Off: Control the unit remotely via a switch or relay, or use the H terminal (battery +) or L terminal (battery −) as needed.
- Paralleling capability: Short-circuit proof design that 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 at elevated temperatures; IP43 protection when installed with downward-facing screw terminals.
- Easy installation: Screw terminals and built-in input fuse (not replaceable) for straightforward setup without special tools.
- Remote shutdown safeguard: Engine shutdown detection stops the converter when the engine isn’t running, preventing unwanted starter battery discharge.
- Electrical specifications: Input 8–17 V; Under Voltage Shut Down 7 V; Under Voltage Restart 7.5 V; Nominal Output 12.2 V; Output Range 10–15 V; Output Tolerance ±0.2 V; Output Noise 2 mV rms; Continuous Output Current 18 A (nominal at 40°C).
The Orion-TR helps prevent low charging voltage and voltage drop over long cable runs, keeping the starter battery protected while the house battery reaches full charge. The Bluetooth interface enables on-the-go monitoring and configuration, and engine-running detection ensures charging only when appropriate. With paralleling capability and broad compatibility for lead-acid and lithium chemistries, it scales to evolving power needs across boats, RVs, and other vehicles.
