Victron Orion-Tr Smart 24/12-20A (240W) Isolated DC-DC Charger

The Orion-TR Smart 24/12-20A (240W) Isolated DC-DC Charger is the perfect addition to your marine or boating setup, ensuring your service batteries are charged efficiently while protecting your starter battery from unwanted discharge. Designed to accommodate a wide range of input and output voltages, this charger excels in environments where voltage drops are common, such as boats with extended cable lengths or those equipped with Euro 5 and Euro 6 smart alternators.

Key Features

Bluetooth Smart Enabled

• Monitor, adjust settings, and update the charger using any Bluetooth-enabled smartphone, tablet, or device.
• Instant Readout: The VictronConnect App displays essential data, including warnings and alarms, directly on the device list page without needing a direct connection.

Fully Programmable

• Customize the battery charge algorithm or select a fixed output to suit your specific needs.
• Smart Alternator Compatibility: Features an engine running detection mechanism to optimize charging.

Adaptive 3-Stage Charge Algorithm

• Bulk: Rapidly charges the battery to a specified level.
• Absorption: Automatically adjusts the absorption time based on the depth of discharge, preventing overcharging for lead-acid batteries and maintaining a fixed absorption time for lithium batteries.
• Float: Maintains the battery at a safe voltage level once fully charged.
• Option to choose a fixed output voltage if preferred.

Smart Alternator Compatibility

The built-in engine shutdown detection ensures the converter stops when the engine is not running, preventing the starter battery from discharging unintentionally.

Remote On/Off Control

Easily integrate a remote on/off switch or relay contact using the two-pole connector. Alternatively, switch the H terminal to battery plus or the L terminal to battery minus or chassis ground.

Paralleling Capability

Connect an unlimited number of units in parallel to increase output current, ensuring flexibility and scalability for your power needs.

Protection Features

• High Temperature Protection: Automatically reduces output current at elevated ambient temperatures to prevent overheating.
• IP43 Protection: Provides robust protection against dust and water spray when installed with screw terminals oriented downward.

Easy Installation

• Utilizes screw terminals for DC connection, eliminating the need for special tools.
• Includes a non-replaceable input fuse for added safety.
