ORION-TR SMART 24/24-17A DC-DC CHARGER

Victron smart isolated DC-DC charger:

The Orion-Tr Smart DC-DC charger is a professional DC to DC adaptive 3-stage charger with built-in Bluetooth. For use in dual battery systems in vehicles or on boats where the (smart) alternator and the start 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 and has an engine running 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 are available up to 400W and unlimited multiple units can be connected in parallel to increase output power. Suitable for high temperatures up to 55°C with a full rated output up to 40°C. 
 
The Orion Smart DC-DC chargers can be used as a power supply or as a battery charger. In charger mode the three-state charge algorithm will increase battery life by properly charging the battery. Especially in the case of vehicles with a smart alternator, or voltage drop caused by long cable runs, controlled charging is indispensable. Controlled charging will also protect the alternator in lithium systems where direct charging can overload the alternator due to the low impedance of the lithium battery. In fixed output mode the output voltage will remain stable independent of the applied load or varying input voltage (within the specified range).

The Orion Smart DC-DC charger can be set up to only provide power when the engine is running. This is possible thanks to the built-in engine shutdown detection. This also prevents the onboard voltage of the vehicle from becoming too low. It is not necessary to intervene in the system of the vehicle, to install a separate motor run sensor or to intervene in the CAN-bus system. Apart from this detection, the Orion Smart DC-DC charger can also be activated by a forced allowed to charge feature, e.g. connected to the ignition switch.

The Orion-Tr Smart DC-DC Charger is fully programmable with the VictronConnect app. 

Features:

Bluetooth Smart enabled- Any Bluetooth enabled smart phone, tablet or other device can be used to monitor, to change settings and to update the charger when new software features become available.

Fully programmable- Battery charge algorithm (configurable) or fixed output. 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 in order 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 absorption time is fixed, default 2 hours.

Alternatively, a fixed output voltage can be chosen.

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 temperature.

IP43 protection- When installed with the screw terminals oriented downwards.

Screw terminals- No special tools needed for installation.

*Please note as per page 10 on the Victron manual, 30A circuit protection is required on both sides of the unit (start battery and auxiliary battery). Minimum cable size is 6mm2.
