Orion-Tr DC-DC Smart Charger Non-Isolated

1. General Description

The Orion Smart DC-DC chargers are specially developed DC-DC converters for controlled charging or fixed output mode. In
charger mode the three-state charge algorithm will increase battery life by properly charging the battery. Especially in the case of
vehicles with an alternator smart control, 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 Smart DC-DC charger is fully programmable with the VictronConnect app. Discover all setup possibilities here: https://
