Victron Energy Orion-Tr Smart DC-DC Charge Booster 12/12

The Orion-Tr Smart DC-DC Charger is a professional DC to DC adaptive 3-stage charger with integrated Bluetooth, known in the market as a charge booster and/or battery-to-battery (B2B) charger.

For use in dual battery systems in vehicles or boats where the (smart) alternator and starting battery are used to charge the service battery. The unit can be monitored and programmed via Bluetooth and can be remotely controlled via a remote on/off switch. It features a motor run detection mechanism.

The Orion-Tr Smart charger can be used in 12V or 24V systems and is suitable for both lead-acid and lithium batteries. Models up to 400 W are available and unlimited units can be connected in parallel to increase output power.

Suitable for high temperatures up to 55 °C with full rated power up to 40 °C.

Suitable for Bluetooth Smart
monitoring, changing settings and updating the charger when new software functions become available can be done with any Bluetooth enabled smartphone, tablet or other device.

Fully programmable
- Battery charging algorithm (configurable) or fixed output.
- Intelligent generator compatibility: engine run detection.

Adaptive 3-stage charging algorithm: constant current - constant voltage - conservation

• For lead acid batteries, it is important to keep the recording time short during shallow discharges to avoid overcharging the battery. After a deep discharge, the constant voltage duration is automatically extended to ensure that the battery fully charges.
• For lithium batteries, the recording time is fixed, by default 2 hours.
• Alternatively, a fixed output voltage can be selected.

Remote on/off
A remote on/off switch or relay contact can be connected to the two-pin connector.
Alternatively, the H terminal (right) of the two-pole plug can be connected to a battery positive terminal or the L terminal (left) of the two-pole plug can be connected to the battery negative terminal (or, for example, to the car body
of a vehicle) can be connected.

All models are short circuit proof and can be connected in parallel to increase output current.
An unlimited number of devices can be connected in parallel.

overtemperature protection
At high ambient temperatures the output current is reduced.

Screw terminals
No special tools are required for installation.
