## Long description

The Victron Orion-Tr ORI121236120 is an isolated DC-DC charger that converts a 12V vehicle supply to a regulated 36V output with a continuous 30A charge current. Designed for charging auxiliary battery systems from a vehicle electrical system, this unit provides galvanic isolation to separate input and output grounds, stable voltage regulation to protect sensitive loads, and a robust current delivery suitable for on-board electronics, accessories and battery banks used in mobile and fleet applications.
Advantages
The isolated topology prevents ground loops and reduces electrical interference between the vehicle battery and the auxiliary 36V system. Built for continuous 30A operation, the charger maintains a steady output current while managing heat and voltage stability. Its regulated output supports safe charging of 36V battery systems and powering of 36V accessories without directly coupling to the 12V input, improving safety and system reliability.
Suitable for
 Charging auxiliary 36V battery banks from a 12V vehicle electrical system
 Powering 36V mobile electronics and accessories in vehicles and boats
 Integration with solar or hybrid power systems requiring an isolated 12V-to-36V converter
 Fleet and commercial vehicle installations where galvanic isolation is required
Key specifications
 Input voltage: nominal 12V vehicle supply
 Output voltage: regulated 36V
 Continuous output current: 30A
 Isolation: galvanic isolation between input and output
 Application: DC-DC charging and power conversion for auxiliary systems
How to use
Install the DC-DC charger according to vehicle and equipment manufacturer guidelines, ensuring secure mechanical mounting and adequate ventilation. Connect the 12V input to the vehicle battery or distribution point using appropriately sized cables and fuses to protect the input circuit. Connect the regulated 36V output to the auxiliary battery or load, observing correct polarity. Verify isolation and proper grounding practices where required, and confirm that the charger settings and wiring match the battery chemistry and system requirements before commissioning.
Usage recommendations
Use appropriately rated cable and protective devices on both input and output sides. Confirm compatibility of battery chemistry and charging profile with the regulated 36V output. Allow sufficient airflow around the unit and follow periodic inspection of connections and mounting to maintain reliable operation in mobile environments.
