Orion-Tr Smart 12/12-30A

The Victron Orion-Tr Smart 12/12-30A is an isolated DC-DC charger designed for dual-battery systems, particularly in vehicles or boats. It charges the service battery from the alternator while being compatible with smart alternators. It can also be used as a power supply.

The Orion-Tr Smart 12/12-30A charger delivers a continuous output current of 30 amperes. In terms of power, this represents:

360 W at an ambient temperature of 40°C. 430 W at an ambient temperature of 25°C. It can also provide a peak of 40 amperes for 10 seconds.

The Orion-Tr Smart 12/12-30A DC-DC charger has an energy efficiency that reaches 87%.

The Orion-Tr Smart 12/12-30A charger is compatible with lead-acid and lithium batteries. It features a three-stage adaptive charging algorithm specifically designed to optimize the lifespan of both battery types.

The Orion-Tr Smart 12/12-30A charger uses a three-stage adaptive charging algorithm: Bulk (rapid charge), Absorption, and Float (maintenance). Here’s how it works:

Bulk: The controller delivers the maximum possible charging current to rapidly recharge the batteries.
Absorption: When the battery voltage reaches the absorption voltage setting, the controller switches to constant voltage mode. For lead-acid batteries, the absorption duration is automatically adjusted based on depth of discharge. For lithium batteries, the absorption duration is fixed (default 2 hours).
Float: A maintenance voltage is applied to the battery to keep it fully charged. A new charging cycle is triggered if the battery voltage drops significantly below this level for at least one minute.
This algorithm is programmable, and eight preprogrammed battery settings are available, configurable via the VictronConnect app.

Yes, the Orion-Tr Smart DC-DC charger can be used not only as a battery charger, but also as a power supply. In power supply mode, the output voltage remains stable, regardless of the load applied or input voltage variations (within the specified range).

Yes, the Orion-Tr Smart 12/12-30A charger is galvanically isolated. It provides 200 VDC isolation between the input, output, and case, which enhances safety and helps prevent ground loops.

The Orion-Tr Smart 12/12-30A charger integrates full electronic protections to ensure safe and reliable operation:

Overheat protection with power reduction when temperature is high.Overload protection.Short-circuit protection.Overheat protection of connectors.

Configuration and monitoring of the Orion-Tr Smart charger are performed via the VictronConnect application. With integrated Bluetooth Smart, you can use a smartphone, Apple or Android tablet, or other devices to customize charge settings, monitor real-time data, and update the controller firmware.

Yes, the Orion-Tr Smart charger has a remote on/off function. You can turn the charger on and off remotely via a dedicated connector or by using the VictronConnect app. This is useful for wired switches or automatic control by a battery management system (BMS).

Yes, it is normal for the Orion-Tr Smart DC-DC charger to emit a noticeable odor when operating at or near its maximum power and heating up. This odor is due to the charger being encapsulated, but it is not harmful to health.

Yes, the Orion-Tr Smart 12/12-30A charger can operate in parallel with other Orion-Tr Smart units. This feature allows increasing the total charging power if needed.

Yes, the Orion-Tr Smart 12/12-30A charger is specifically designed to be compatible with smart alternators, including those in Euro 5 and Euro 6 vehicles. These alternators, controlled by the engine ECU, deliver a variable output voltage and can shut down when not needed. The charger manages these variations to ensure optimal charging of the service battery.

Yes, the Orion-Tr Smart charger includes an engine-running detection mechanism. This function separates the starter battery from the service battery when the engine is off, preventing the inverter from discharging the starter battery. No intervention in the vehicle's system or installation of external sensors is required.

The Orion-Tr Smart 12/12-30A model is designed for systems with a nominal input voltage of 12V and provides an output voltage of 12V. It is therefore a 12V to 12V DC-DC converter.

For correct installation, the Orion-Tr Smart charger must be mounted:

Vertically on a non-flammable surface.
With power terminals facing downward.

To ensure optimal cooling of the Orion-Tr Smart charger, a minimum clearance of 10 cm must be maintained above and below the unit.

It is important not to install the Orion-Tr Smart charger:

Directly above the battery to avoid damage from battery gases.In a humid environment.Close to chemicals, plastic parts, curtains or other textiles, as the charger may become hot during operation.In areas where gas or dust explosions could occur.

For battery connections, it is recommended to use flexible multistrand copper cables. The diameter of individual strands in the cable must not exceed 0.4 mm (0.016 in) or have a cross-sectional area greater than 0.125 mm² (AWG26). For example, a 16 mm² cable should have at least 122 strands (class 5 or higher per VDE 0295, IEC 60228, and BS6360).

Additionally, the installation must absolutely include a fuse. Specific fuse recommendations are detailed in the "Cable and fuse recommendations" section of the product manual.

It is critical to comply with these specifications to avoid high contact resistance, severe overheating, and fire risk.

No, the Orion-Tr Smart DC-DC charger is not protected against reverse polarity. It is therefore essential to carefully check the polarity before and during the battery connection to avoid damaging the device.
