1. General Description
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.
