The Victron Energy Orion-Tr Smart DC-DC Charger is a professional DC-to-DC adaptive 3-stage charger with built-in Bluetooth. It's designed for use in dual battery systems in vehicles or on boats where the alternator and the start battery are used to charge the service battery. The unit can be monitored and programmed via Bluetooth and can be remotely controlled via a remote on/off switch.

The Orion-Tr Smart Charger can be used in 12V or 24V systems and is suitable for both lead acid and lithium batteries. Unlimited multiple units can be connected in parallel to increase output power. Suitable for high temperatures up to 55°C with a full rated output up to 40°C.

Bluetooth Smart Enabled – Any Bluetooth enabled smart phone, tablet, or other device can be used to monitor and change settings and to update the charger when new software features become available. The VictronConnect App can display key data, including warnings and alarms, on the device list page without the need to connect to the product.

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).

Short-Circuit Proof

Can be Paralleled to Increase Output Current

High-Temperature Protected – The output current will reduce at high ambient temperature.
