Victron Energy Orion-Tr Smart 24/12-20A (240W) Isolated DC-DC Charger for Vehicles and Marine Applications

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

The Orion-Tr Smart isolated DC-DC charger serves as a DC-DC battery charger or a power supply (also designed for use as a constant voltage source), offering a wide input and output voltage range. This is especially significant in the case of vehicles with a Euro 5 or Euro 6 smart alternator, which often supplies too low charging voltage even when the engine is running or when extended cable lengths, as is often the case in boats and RVs, lead to voltage drops. In such scenarios, precise and controlled charging is imperative to fully charge the service battery while protecting the starter/input battery from discharge.

Bluetooth Smart Enabled

• Any Bluetooth-enabled smartphone, tablet, or other device can be used to monitor, change settings, and update the charger when new software features become available
• Instant Readout: The VictronConnect App can display key data, including warnings and alarms, on the device list page without the need to connect to the product

Fully programmable

• Battery charge algorithm (configurable) or fixed output. Orion-Tr Smart 12/12-30 Orion-Tr Smart 12/12-30
• Smart Alternator Compatibility: engine running detection mechanism

Adaptive 3-Stage Charge Algorithm: Bulk Absorption Float

• For lead-acid batteries, it is important that during shallow discharges the absorption time is kept short to prevent overcharging of the battery. After a deep discharge, the absorption time is automatically increased to make sure that the battery is completely recharged
• For lithium batteries, the absorption time is fixed; the default is 2 hours
• Alternatively, a fixed output voltage can be chosen

Suitable for Use in Vehicles with a Smart Alternator (Euro 5 and Euro 6 Engines)

The built-in engine shutdown detection will stop the converter when the engine is not running. This prevents unwanted discharge of the starter battery (see manual for details).

Remote On/Off

A remote on/off switch or relay contact can be connected to a two-pole connector. Alternatively, the H terminal (right) of the two-pole connector can be switched to battery plus, or the L terminal (left) of the two-pole connector can be switched to battery minus (or the chassis of a vehicle, for example).

All Models Are Short Circuit Proof and Can Be Paralleled to Increase Output Current

An unlimited number of units can be connected in parallel.

High Temperature Protected

The output current will reduce at high ambient temperatures.

IP43 Protection

The Victron Energy Orion-Tr Smart 24/12-20A (Part Number: ORI241224120) is a versatile isolated DC-DC charger designed for reliable power conversion in vehicles, boats, and RVs. It functions as a DC-DC battery charger or a constant voltage power supply, providing a wide input voltage range from 16 to 35 volts to accommodate various power sources. This feature is especially beneficial for vehicles equipped with Euro 5 or Euro 6 smart alternators, which often supply insufficient charging voltage during engine operation or extended cable runs, leading to voltage drops. The Orion-Tr Smart ensures the service battery charges fully while safeguarding the starter or input battery against discharge, maintaining optimal battery health and performance.

The charger is Bluetooth Smart enabled, allowing users to monitor and adjust settings conveniently via the VictronConnect app on any Bluetooth-compatible smartphone or tablet. The app provides real-time data, warnings, and alarms directly on the device list page, eliminating the need for wired connections. Fully programmable, the Orion-Tr Smart offers customizable battery charge algorithms or a fixed output mode, making it adaptable to various battery chemistries, including lead-acid and lithium batteries. Its smart alternator compatibility includes engine running detection, which automatically halts charging when the engine stops, preventing unnecessary battery drain. The adaptive three-stage charge algorithm dynamically adjusts the absorption time based on the battery's discharge level, optimizing charging efficiency and longevity. For lithium batteries, a fixed two-hour absorption time is standard, with the option to set a fixed output voltage.

The Orion-Tr Smart is suitable for use in vehicles with smart alternators, thanks to its built-in engine shutdown detection. It features remote on/off capability via a switch or relay, providing flexible control options for integration into existing systems. Multiple units can be paralleled to increase output current, with no limit on the number of connected units, enabling scalable power solutions. The device is protected against high temperatures by reducing output current at elevated ambient temperatures and features IP43 protection when installed with screw terminals downward, ensuring durability in demanding environments. The product's robust construction includes screw terminals for easy installation, with an input fuse (not replaceable). Its efficiency rating is 88%, and it offers galvanic isolation of 200 VDC between input, output, and case for safety and interference reduction. Operating within a temperature range of -20°C to +55°C, the Orion-Tr Smart is designed for reliable, continuous operation.
