Orion-Tr Smart DC-DC Charger Isolated 1. General Description The Orion-Tr Smart DC-DC Charger Isolated 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.
Orion-Tr Smart DC-DC Charger Isolated 2. Features Smart alternator compatibility Vehicle manufacturers are now introducing smart ECU (Engine Control Unit) controlled alternators to increase fuel efficiency and reduce emissions. Smart alternators deliver a variable output voltage and are shut down when they’re not needed. The converter has an engine running detection mechanism.

Danger of explosion from sparking Danger of electric shock • Please read this manual carefully before the product is installed and put into use •...
Orion-Tr Smart DC-DC Charger Isolated 4. Installation 4.1. General • Mount vertically on a non-flammable surface, with the power terminals facing downwards. Observe a minimum clearance of 10 cm under and above the product for optimal cooling. • Mount close to the battery, but never directly above the battery (in order to prevent damage due to gassing of the battery). 4.2.
Orion-Tr Smart DC-DC Charger Isolated Figure 2: Typical connection setup as charger 4.4. Connection remote on-off The recommended use of the remote on-off is: a) A switch wired between the L-H pins (On-level impedance between L-H pins: < 500kΩ) b) A switch wired between (input/starter) battery plus and H-pin (on level: > 3V) c) A switch between the L-pin and (input/starter) ground (on level: <...
Orion-Tr Smart DC-DC Charger Isolated 4.5. Engine shutdown detection override In charger mode the “engine shutdown detection sequence” determines if conditions are met to enable charging, see chapter 5. The “engine shutdown detection override” forces the charger to allow charging independently of the engine shutdown detection. Engine shutdown detection override is activated by applying >7V to the remote L-pin.

Orion-Tr Smart DC-DC Charger Isolated 5. Engine shuthown detection The engine shutdown detection mechanism simplifies your ORION-Tr DC-DC Charger system by detecting if the engine is running without wiring additional switches or sensors. The factory default setting will work with most regular and smart alternators but can be re-configured with the VictronConnect App.

Orion-Tr Smart DC-DC Charger Isolated Figure 9: Engine shutdown detection setup menu The following settings can be changed with VictronConnect: The default values displayed are for the 12V input models. Those values are scaled depending on the input voltage of the model. E.g. for 24V input models, the default values displayed on the manual should be multiplied by 2.

Orion-Tr Smart DC-DC Charger Isolated If the low voltage period exceeds tshutdown charging will be disabled on engine shutdown detection. • Voltage drop across the input cable: As seen in “engine shutdown detection sequence 1→3”, V will be lowered by Vcable. When the alternator voltage drops fast (smart alternator) the charge-control needs some time to reduce charge current and keep V at V...
