Victron smart isolated DC-DC charger:

The Orion-Tr Smart DC-** charger is a professional DC to DC ******** 3-stage charger with built-in Bluetooth. For use in **** battery ******* in vehicles or on boats ***** the (smart) ********** and the ***** battery *** used to charge the service battery. The unit can be monitored and programmed *** Bluetooth and can ** remotely ********** via a remote on/off switch and has an engine running ********* mechanism.

The ***** Tr-***** charger can ** used in 12V or 24V systems and is suitable for both lead acid and lithium batteries. Models are available up to 4*** and unlimited multiple units can ** connected in parallel to increase output power. Suitable for high ************ up to 55°C with a full ***** output up to 40°C. 
 
The Orion Smart DC-DC chargers can be used as a power supply or ** a battery charger. In charger mode the three-***** charge algorithm will increase ******* life by properly charging the battery. ********** in the case of vehicles with a ***** alternator, or ******* drop caused by **** cable runs, ********** charging is indispensable. ********** ******** will also protect the alternator ** lithium ******* where direct charging can overload the alternator due to the low impedance of the lithium battery. In fixed output mode the output voltage will ****** stable independent of the ******* load or varying input voltage (within the specified range).

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

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

Features:

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

Fully programmable- Battery charge ********* (configurable) or fixed output. ***** alternator compatibility: engine running detection mechanism.

Adaptive 3-***** charge algorithm: bulk – absorption – float- *** **** acid batteries it ** important that during shallow discharges the absorption time is kept short in order to prevent overcharging of the battery. ***** a deep discharge the absorption time ** ************* increased to make sure that the battery is completely recharged.

For lithium ********* absorption time ** fixed, default 2 hours.

Alternatively, a ***** ****** voltage can be chosen.

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

All models are short circuit proof and *** be paralleled to increase output current-  An unlimited number ** units can be connected in parallel.

**** 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 *** page 10 on the Victron manual, 60A circuit protection is required on both sides of the unit (start battery *** auxiliary battery). Minimum ***** size is 10mm2.
