Convertitore DC-DC Victron Energy Orion-Tr 24/12-9A 110W 12V — convertitore step-down isolato

The Victron Energy Orion-Tr 24/12-9A 110W DC-DC converter is an isolated step-down converter that transforms a 24 V input into a regulated 12 V output with up to 9 A continuous current and 110 W maximum power. Designed for vehicle and marine electrical systems, this unit provides a stable 12 V supply for electronics and accessories while isolating input and output grounds to reduce electrical noise and prevent ground loops. The converter is intended for applications where reliable battery-to-battery conversion or a dedicated 12 V rail is required from a 24 V source.

Advantages

The isolated design eliminates common-ground issues and helps protect sensitive 12 V equipment from interference and voltage transients originating on the 24 V side. The device delivers a regulated output under varying input and load conditions, supporting continuous operation at rated power. Compact enclosure and mounting options facilitate installation in tight spaces typical of vehicles and boats. Built-in protections such as overcurrent and thermal limiting contribute to long-term reliability.

How to use

Install the converter in a dry, ventilated location close to the 24 V source and the 12 V loads, ensuring secure mounting and adequate clearance for cooling. Connect the positive and negative input terminals to the 24 V battery or supply, and connect the regulated 12 V output to the 12 V distribution or battery being charged, observing correct polarity. Verify that input and output wiring is sized for the expected current and fitted with appropriate fusing on the source side. After powering up, confirm the output voltage and load behavior; the converter will regulate the 12 V output and provide protection against overload and overheating.

Recommendations

Use correctly sized wiring and a fuse on the 24 V input to protect against short circuits. Keep the converter away from direct exposure to water and corrosive environments unless installed in a suitably protected enclosure. For installations involving charging of a secondary battery, verify compatibility with the battery type and charging requirements to ensure correct charging behaviour and avoid undue cycling.
