DC-DC Converter Orion-Tr Smart 12V to 12V 30A Non-isolated, Victron Energy ORI121236140

The Orion-Tr Smart DC-DC converter 12V to 12V 30A from Victron Energy is a non-isolated step-down/regulated power converter designed for vehicle and marine electrical systems with a common ground. It accepts a nominal 12 V input and provides a stable, regulated 12 V output capable of supplying up to 30 A continuous. The unit is intended to power sensitive electronics, charge auxiliary batteries and manage loads where the input and output share the same ground, while offering compact dimensions and robust construction suitable for confined installation spaces.

Advantages

The converter provides precise voltage regulation and current capability to protect connected equipment and batteries. Its non-isolated design reduces size and weight while maintaining efficient energy transfer in common-ground systems. Integrated communication options allow monitoring and configuration to optimise charging behaviour and system integration. The device is built to withstand the vibration and environmental demands typical of vehicle and marine installations.

Suitable for

• Powering sensitive 12 V electronics in cars, trucks and boats
• Charging auxiliary or starter batteries from a vehicle 12 V supply
• Supplying stable power to communication and navigation equipment
• Integration into mobile power systems with a shared ground

Key specifications

• Input voltage: nominal 12 V vehicle/marine system compatibility
• Output voltage: regulated 12 V output suitable for 12 V loads
• Maximum continuous output current: 30 A
• Conversion type: non-isolated DC-DC converter
• Monitoring and configuration: support for CAN and VE.Direct communication interfaces
• Form factor: compact, vibration-resistant housing for constrained installation spaces

How to use

Install the converter in a dry, ventilated location with a common ground connection between the input and output systems. Connect the positive and negative input leads to the vehicle or vessel 12 V supply and connect the regulated 12 V output to the auxiliary battery or loads. Follow the manufacturer’s wiring and fuse recommendations to protect cables and devices. Use the available communication interface to monitor voltage, current and temperature and to select appropriate charging profiles for the connected battery type.

Recommendations

Ensure correct grounding and cable sizing to minimise voltage drop and heat build-up. Place the unit where airflow is adequate and avoid mounting directly on heat-sensitive surfaces. When used to charge batteries, configure the converter’s charge parameters to match battery chemistry for optimal battery life and performance.
