The Victron Orion-Tr Smart 24/24-17A (400W) Non-isolated DC-DC Charger is a powerful DC-DC charge booster designed for the intelligent charging of 24V batteries from 24V systems.
Ideal for boats, trucks, buses, motorhomes, and industrial power systems, it provides stable and efficient voltage regulation—even with fluctuating on-board voltage.
With 17A charging current and 400W power, the Orion-Tr Smart offers reliable and adaptable charging performance.
Thanks to the intelligent, adaptive 3-stage charging algorithm (bulk, absorption, float), batteries are optimally charged and protected, regardless of battery type – whether lithium, AGM, gel, or wet batteries.
The charge booster can be easily monitored and configured via Bluetooth Smart using the VictronConnect app.
There, parameters such as charging voltage, temperature compensation, and charging profiles can be individually adjusted – including real-time monitoring of voltage, current, and status.
The Orion-Tr Smart 24/24-17A is not galvanically isolated, which makes it particularly compact and efficient.
Multiple devices can be connected in parallel to increase the total charging current.
With its IP43 protection class and passive cooling, it is ideal for mobile, marine, and industrial environments.
