Built-In Protection Functions The Victron Orion-Tr DC-DC converter incorporates essential protection features to ensure safe and reliable operation. These include: Output Short Circuit Protection • Over Temperature Protection. These safeguards help prevent damage to the unit and connected equipment under fault conditions. Common Questions What does "non-isolated" mean for this converter? A non-isolated converter means that the input and output share a common electrical ground. This is typical for many vehicle and battery systems where a single ground reference is used throughout. It's important to ensure your system design is compatible with a common ground. Can I use this converter to charge a 12V battery from a 24V system? Yes, the Victron Orion-Tr 24/12-10A has an adjustable output voltage (10-15V), allowing it to be configured as a 12V battery charger. This is useful for maintaining a 12V auxiliary or starter battery in a 24V primary system. How can I increase the output current if 10A is not enough? This Victron Orion-Tr model supports parallel operation. You can connect up to five identical units in parallel to increase the total available output current, providing greater power for larger 12V loads. What types of 12V equipment can this converter power? It can power a wide range of 12V DC equipment, including LED lighting, communication radios, navigation electronics, small pumps, fans, and other sensitive electronic devices, provided their combined current draw does not exceed 10A (120W). Installation Notes Ensure the input voltage from your 24V source is within the specified range of 18-35V DC. Mount the converter in a well-ventilated area to prevent overheating, ensuring adequate airflow around the unit. Use appropriate cable gauges for both input and output connections to minimise voltage drop and ensure safety. Pay close attention to correct polarity when wiring the input and output connections to avoid damage. As a non-isolated unit, verify that a common ground between the 24V input and 12V output is suitable for your system's electrical architecture. Before You Buy Verify Voltage Requirements: Confirm your input source is 24V DC nominal and your loads require 12V DC. Calculate Power Needs: Ensure the total continuous current draw of your 12V equipment does not exceed 10A (120W). Check Grounding: Understand the implications of a non-isolated converter and confirm it aligns with your system's grounding scheme. Consider Future Expansion: If higher current is needed, remember this model supports parallel operation with up to five units. Professional Installation: For complex systems or if unsure, consult a qualified electrician or solar installer. Always verify product specifications and compatibility with your specific system requirements before purchase and installation. Professional installation is recommended.
