Victron Orion-TR Smart 12/12-18A 18A (220W) Isolated DC-DC Charger or Power Supply

The Orion-TR Smart 12/12-18A (220W) Isolated DC-DC Charger is a versatile power solution tailored for marine and boating applications. Whether used as a dependable DC-DC battery charger or a stable constant voltage power supply, it ensures optimal performance even in vessels equipped with smart alternators and extended cable setups prone to voltage drops. This intelligent charger guarantees the full charging of your service battery while protecting your starter or input battery from unwanted discharge.

Key Features

• Wide Input and Output Voltage Range: Compatible with Euro 5 and Euro 6 smart alternators, ensuring effective charging despite low alternator voltages or long cable runs.
• High Efficiency: Achieves up to 87% efficiency, minimizing energy loss and ensuring reliable performance in marine environments.
• Galvanic Isolation: Provides 200 VDC isolation between input, output, and case for enhanced safety and reliability.

Bluetooth Smart Enabled

Easily monitor and control your charger using any Bluetooth-enabled smartphone, tablet, or device. The VictronConnect App allows you to:

• Monitor real-time performance and key data.
• Change settings and configure charge algorithms.
• Update the charger’s firmware with new software features as they become available.

Instant Readout: View warnings and alarms directly on the device list page without needing to connect to the charger.

Fully Programmable

• Customizable Charge Algorithms: Configure battery charge algorithms to suit your specific battery type or select a fixed output for consistent performance.
• Smart Alternator Compatibility: Features an engine running detection mechanism to optimize charging based on engine status.

Adaptive 3-Stage Charge Algorithm

Ensures your batteries are charged efficiently and safely through three distinct stages:

1. Bulk: Rapidly charges the battery to a set voltage.
2. Absorption: Maintains the charge voltage to fully recharge the battery without overcharging.
3. Float: Maintains the battery at a safe voltage to prevent discharge and prolong battery life.

Specifics:

• Lead-Acid Batteries: Shorter absorption times for shallow discharges and extended times for deep discharges to ensure complete charging without overcharging.
• Lithium Batteries: Fixed absorption time, typically set to 2 hours, providing consistent charging for lithium batteries.
• Fixed Output Option: Alternatively, select a fixed output voltage for applications requiring constant voltage.

Smart Alternator Compatibility

Designed for vehicles with smart alternators (Euro 5 and Euro 6 engines), the charger includes a built-in engine shutdown detection feature. This stops the converter when the engine is not running, preventing unwanted discharge of the starter battery.

Remote On/Off Control

Easily manage the charger’s power state with a remote on/off switch or relay contact connected to a two-pole connector. You can also switch the H terminal to battery plus or the L terminal to battery minus (or vehicle chassis) for convenient remote control.

Paralleling Capability

The charger is short circuit proof and can be connected in parallel to increase the total output current. There is no limit to the number of units that can be paralleled, allowing for scalable power solutions tailored to your specific needs.

Protection Features

• High Temperature Protection: Automatically reduces output current at high ambient temperatures to prevent overheating.
• IP43 Protection: Ensures durability and reliability when installed with screw terminals oriented downward, offering protection against dust and water spray.

Easy Installation

Installation is straightforward with screw terminals that require no special tools. The charger includes an input fuse (non-replaceable) for added safety.
