Product Overview
The Victron Energy Orion 24/12-Volt 70 Amp DC-DC Converter is designed for high-efficiency voltage conversion, stepping down 24-Volt DC input to a stable 12-Volt DC output. It is suitable for various applications including motor, marine, electronic systems, and off-grid setups.
Key Features:
- High Conversion Efficiency: Up to 92% efficiency ensures minimal power loss.
- Wide Input Voltage Range: Accepts 18-Volt to 35-Volt DC input.
- Stable Output Voltage: Provides 10-Volt to 15-Volt DC output.
- Remote On-Off Connector: Allows for external control, eliminating the need for a high-current switch in the input wiring.
- Adjustable Output: Can be used as a battery charger for 12-Volt batteries in a 24-Volt system.
- Parallel Operation: Up to five units can be connected in parallel to increase output current.

Setup and Installation
The Orion DC-DC Converter is designed for straightforward installation. Follow these general guidelines:
- Mounting: Securely mount the converter in a well-ventilated area using four screws. Ensure the mounting surface is stable and can support the device's weight.
- Wiring: Connect the 24-Volt DC input (18-35V) from your battery bank to the input terminals. Connect your 12-Volt DC appliances to the output terminals (10-15V). Ensure correct polarity (positive to positive, negative to negative/ground).
- Remote On-Off: If using the remote on-off feature, connect a low-power switch or engine run/stop switch to the designated remote on-off connector. This allows for convenient control without high-current switching.
- Fusing: Install appropriate fuses or circuit breakers on both the input and output lines to protect the converter and connected devices from overcurrent.

Operating Instructions
Once properly installed, the Victron Energy Orion DC-DC Converter operates automatically to provide stable 12-Volt power from a 24-Volt source.
- Power On/Off: If the remote on-off feature is connected, use the external switch to activate or deactivate the converter. Otherwise, the unit will power on when input voltage is present.
- Load Management: The converter can supply up to 70 Amps continuously. Monitor your total 12-Volt load to ensure it does not exceed the converter's capacity.
- Battery Charging: Models with adjustable output can function as a battery charger. Refer to the detailed product sheet for specific adjustment procedures if using this feature.
- Parallel Operation: For higher current requirements, up to five units can be connected in parallel. Consult the wiring diagram for correct parallel connection setup.

Maintenance
The Victron Energy Orion DC-DC Converter is designed for reliability and requires minimal maintenance. Regular checks can help ensure optimal performance and longevity.
- Visual Inspection: Periodically inspect the converter for any signs of damage, loose connections, or overheating.
- Cleanliness: Keep the unit clean and free from dust and debris to ensure proper airflow and cooling. Use a dry cloth for cleaning.
- Ventilation: Ensure that the area around the converter remains unobstructed to allow for adequate ventilation.
- Connection Integrity: Check all electrical connections for tightness, especially after initial installation and during routine maintenance.
Troubleshooting
If you encounter issues with your Victron Energy Orion DC-DC Converter, refer to the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| No output voltage | No input voltage; remote on-off switch off; blown fuse/breaker | Check input power; activate remote switch; check and replace fuses/reset breakers. |
| Low output voltage | Overload; poor connections; input voltage too low | Reduce load; check and tighten connections; verify input voltage is within range (18-35V). |
| Overheating | Insufficient ventilation; excessive load | Ensure proper airflow around the unit; reduce connected load. |
If the problem persists after attempting these solutions, contact Victron Energy support or a qualified technician.
