Victron Orion-Tr Smart 12/12-18A (12V INPUT/12V OUTPUT) Isolated DC-DC charger

WARNING - (12V INPUT ONLY AND 12V OUTPUT ONLY) - Not Interchangeable! The unit will be irrepairably damaged if the correct battery voltages are not used.

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.



Input fuse (not replaceable)


Warranty: 2 Years
