Victron Orion-Tr Smart 24/12-30A (360W) Non-isolated DC-DC charger
The Orion-Tr Smart DC-DC charger is a professional DC to DC adaptive 3-stage charger with built-in Bluetooth. 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. Models are available up to 400W and 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 smartphone, tablet or other devices 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)
Victron DC-DC Chargers: Non-Isolated vs Isolated:
The main difference with an isolated DC-DC charger is the connection to each battery as there is only one negative connection to the battery. Plus, there is no internal connection between the negatives in the battery. Some systems require an isolated DC to DC charger, this can be some of the reasons:
- Typically, marine application with limited corrosion
- Decrease noise from one battery system that will affect another battery system
Either unit can be used for systems that don’t require isolation, but the non-isolated requires one less wire to be installed.
One example of a non-isolated system is an automotive system, such as both batteries are negative and connected to the chassis of a vehicle. The system is non-isolated but either unit will suit.
No Solar Regulator in the DC-DC Charger:
Victron have chosen to separate the charger and the solar regulators, these are the advantages:
- You can choose the correct solar regulator to match your panels with the best efficiency for the solar charging
- The solar can be charging into the battery system simultaneously with the onboard vehicle charging
- Without a solar regulator, the DC-DC charger will stay cheaper
