Victron Orion-Tr Smart 24/12-30A (360W) Isolated DC-DC Charger
Victron Orion-Tr Smart 24/12-30A (360W) Isolated DC-DC Charger
Steps a 24V starter/alternator voltage down to charge a 12V auxiliary battery bank - common in heavier trucks and commercial vehicles running 24V electrics but fitted with a 12V accessory or house system.
Galvanic isolation between circuits
Fully isolated design with no shared chassis ground between the 24V input and 12V output sides, reducing corrosion risk and electrical noise coupling - particularly useful where the two systems serve genuinely separate purposes.
Smart alternator compatible
Built-in engine-running detection means the charger only draws from the alternator when it's actually supplying power, preventing starter battery drain on vehicles fitted with variable-voltage smart alternators.
Bluetooth configuration via VictronConnect
Configure the charge algorithm for lead-acid or lithium, monitor live status, and update firmware - all from your phone over built-in Bluetooth, no separate dongle needed.
