Victron Energy Orion-Tr DC-DC Converter - Isolated 12/12-18A
This professional-grade Victron Energy Orion-Tr DC-DC Converter offers an efficient 18A output and...This professional-grade Victron Energy Orion-Tr DC-DC Converter offers an efficient 18A output and operates seamlessly in 12V systems, supporting both lead-acid and lithium batteries. It can be easily expanded by connecting multiple units in parallel for increased output power. Designed for durability, it withstands high temperatures up to 55°C, maintaining full rated output up to 40°C. The converter features a remote on-off function, adjustable output voltage (also usable as a battery charger), and short-circuit protection. It boasts IP43 protection when installed with screw terminals facing downwards and includes convenient screw terminals for installation. Galvanic isolation of 200 V dc provides safety between input, output, and case. The operating temperature range is -20 to +55°C, with a derating of 3% per °C above 40°C. Dimensions are 130 x 186 x 70 mm with a weight of 1.3 kg.
This guide is for users of the Victron Energy Orion-Tr DC-DC Converter, designed for efficiently converting 12V DC power in various applications. The Orion-Tr provides a reliable 18A output, making it ideal for charging batteries and powering devices in mobile and off-grid setups. A key point to note is the derating of output at higher temperatures; ensure adequate ventilation in warm environments.

Extended Product Information
FAQs
What is the meaning of galvanic isolation?
Galvanic isolation means there is no direct electrical connection between the input and output circuits, providing safety and preventing ground loops.
Can I use this converter to charge my lithium batteries?
Yes, the Orion-Tr is compatible with lithium batteries. Ensure the output voltage is set correctly for the charging profile of your lithium battery.
How do I connect multiple units in parallel?
Connect the input terminals of all units to the same 12V source, and connect the output terminals of all units to the load or battery. Ensure all connections are secure and use appropriately sized wiring.
What is the remote on-off function?
The remote on-off function allows you to switch the converter on and off remotely, which can be useful for integrating it into a larger power management system.
What happens if the unit overheats?
The unit has built-in protection against overheating. If the temperature exceeds safe levels, the output will be reduced or the unit will shut down to prevent damage. Ensure proper ventilation.
What is the IP43 rating?
IP43 indicates the level of protection against solid objects and water. The '3' means that the unit is protected against spraying water. This rating is achieved when the unit is installed with the screw terminals facing downwards.
Troubleshooting
Converter not turning on.
Check the input voltage and the remote on-off connection. Ensure the input voltage is within the specified range and that the remote on-off signal is correct if used.
Low output voltage.
Verify the input voltage. Check the output voltage setting. Ensure that the unit is not operating at a temperature above 40°C, as the output is derated above this temperature.
Converter overheating.
Ensure adequate ventilation. Reduce the load if the unit is operating near its maximum capacity. Check for any short circuits on the output side.
Unit shuts down intermittently.
Check for overloads or short circuits. Reduce the load or replace the unit if the issue persists.

Setup, Compatibility & Care
Setup:
Mounting: Install the converter with screw terminals facing downwards to achieve IP43 protection.
Wiring: Use appropriate gauge wires for the input and output current. Securely connect wires to the screw terminals.
Connections: Connect the input to the 12V DC source and the output to the load or battery.
Remote On-Off: Connect the remote on-off terminal if remote control is desired.
Compatibility:
Batteries: Compatible with both lead-acid and lithium batteries. Ensure the output voltage is correctly set for your battery type.
Parallel Operation: Up to five units can be connected in parallel. Ensure that the input and output wiring is capable of handling the increased current.
Operating Environment: Operates within a temperature range of -20°C to +55°C. The full output is maintained up to 40°C. Above 40°C, the output is derated.
Care:
Inspection: Regularly inspect the unit for any signs of damage or loose connections.
Ventilation: Ensure adequate ventilation, especially in high-temperature environments, to prevent overheating.
Cleaning: Clean the unit with a dry cloth or a slightly damp cloth. Avoid using harsh chemicals or solvents.
