Operating & Power Guidance
The Victron Orion 24/12-70 is designed for flexible power management in 24V DC systems requiring a stable 12V DC supply. Its adjustable output voltage allows it to function not only as a reliable step-down converter but also as a single-stage battery charger for 12V auxiliary or starter batteries.
The remote on/off feature simplifies system integration, allowing the converter to be controlled by a low-power switch or an engine run/stop signal, eliminating the need for high-current switching in the main input wiring.
Typical Applications
| Application | Description |
|---|---|
| Commercial Vehicles | Powering 12V accessories like radios, navigation, and lighting in trucks and buses with 24V systems. |
| Marine Systems | Supplying 12V electronics such as navigation equipment, communication radios, and LED lighting on boats with 24V battery banks. |
| Off-Grid & Solar | Integrating 12V loads into 24V solar battery storage systems for enhanced efficiency and compatibility. |
| RV & Camper Conversions | Running 12V appliances and systems from a 24V house battery setup. |
Built-In Protection Functions
The Victron Orion 24/12-70 DC-DC Converter incorporates several protection features to ensure safe and reliable operation. These include under-voltage shutdown to protect connected batteries, over-temperature protection which reduces output current when internal temperatures rise, short circuit protection that disconnects output during fault conditions, and reverse polarity protection to prevent damage from incorrect battery connections.
Common Questions
Q: Is this converter isolated?
A: No, the Victron Orion 24/12-70 is a non-isolated DC-DC converter, meaning the input and output share a common ground.
Q: Can I use this to charge a 12V battery from my 24V system?
A: Yes, models with adjustable output, like the Orion 24/12-70, can be used as a single-stage battery charger for a 12V starter or auxiliary battery in a 24V system.
Q: How many of these converters can I connect in parallel?
A: Up to five units of the Victron Orion 24/12-70 can be connected in parallel to increase the total output current for higher power demands.
Q: Does it have a remote on/off feature?
A: Yes, it includes a remote on/off connector, which can be operated with a low-power switch or an engine run/stop switch for convenient system control.
Installation Notes
- For optimal performance and safety, mount the converter vertically on a non-flammable surface, ensuring power terminals face downwards.
- Allow a minimum clearance of 10 cm (approximately 4 inches) above and below the product for adequate cooling.
- Position the converter close to the battery, but never directly above it, to prevent potential damage from battery gassing.
- Always ensure correct polarity when connecting cables. Reverse polarity can damage the device and is not covered under warranty.
- The input positive connection should be protected by an appropriately rated fuse. Consult the manufacturer's manual for specific recommendations.
- For detailed installation instructions, wiring diagrams, and fuse recommendations, always consult the official Victron Energy manual for this specific model.
Before You Buy
- Verify that your input voltage source is a 24V DC system and your target load or battery requires a 12V DC supply.
- Confirm the continuous current draw of your 12V equipment does not exceed 70 Amps (or 85 Amps peak) to ensure compatibility.
- Consider if a non-isolated converter is suitable for your application, particularly regarding grounding requirements.
- Review the physical dimensions (66 x 89 x 196 mm) to ensure adequate space for installation and ventilation.
- For battery charging applications, note that this unit provides a single-stage output. For multi-stage charging, consider Victron's Smart DC-DC Chargers.
Specifications are subject to change by the manufacturer. Always verify the model, SKU, and compatibility with your specific system requirements against the latest manufacturer's datasheet or manual before purchase.
