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

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 battery charger or constant voltage power supply, supporting a wide input voltage range from 16 to 35 volts. This flexibility ensures optimal charging and power supply, even in environments with low alternator voltage or extended cable runs that cause voltage drops. Its intelligent design helps fully charge the service battery while safeguarding the starter or input battery from discharge, making it suitable for modern vehicles with Euro 5 and Euro 6 smart alternators that often supply lower voltage levels during operation.

The Orion-Tr Smart charger features Bluetooth connectivity, enabling users to monitor, configure, and update the device remotely via the VictronConnect app on any Bluetooth-enabled smartphone, tablet, or compatible device. This real-time data display includes warnings and alarms, providing comprehensive oversight without the need for direct connection. Fully programmable, the charger allows customization of the battery charge algorithm or fixed output voltage, accommodating different battery chemistries such as lead-acid and lithium-ion. It incorporates an adaptive three-stage charge algorithm—Bulk, Absorption, and Float—optimizing charging cycles for battery longevity and performance. For shallow discharges, the absorption time is minimized to prevent overcharging, while deep discharges trigger automatic adjustments to ensure a complete recharge.

Designed to work seamlessly with vehicles equipped with Euro 5 and Euro 6 engines, the built-in engine shutdown detection prevents unwanted discharge by stopping the converter when the engine is off. The device supports remote operation through a dedicated on/off switch or relay contact, which can be wired to a vehicle’s battery system or chassis for remote control. Its modular design allows units to be paralleled indefinitely, increasing the overall output current as needed. The charger is protected against high temperatures, with output current reducing at elevated ambient temperatures to maintain safety and reliability. Constructed with IP43 protection when mounted appropriately, it features durable screw terminals for easy installation without special tools.

Operationally, the Orion-Tr Smart charger provides high efficiency at 88%, with a maximum continuous output power of 300 watts at 25°C. It delivers a nominal output voltage of 12.2 volts, with adjustable output voltage settings and low noise levels for sensitive electronics.
