This fixed output voltage is suitable for powering 12V loads that require a stable supply and can also help maintain the charge of 12V battery systems within a 24V setup. Its non-isolated design means the input and output negative terminals are common, which is typical for many vehicle and marine electrical systems. The remote on/off feature allows for integration with existing control systems, such as an engine run/stop switch, simplifying power management without requiring a high-current switch in the main wiring. Typical Applications Application Description Commercial Vehicles Powering 12V accessories, radios, and communication equipment from a 24V truck or bus electrical system. Marine Systems Supplying stable 12V power for navigation electronics, stereos, and other onboard devices on 24V vessels. Off-Grid & Solar Systems Converting 24V battery bank power to 12V for specific loads or maintaining 12V auxiliary batteries. Industrial Equipment Providing regulated 12V power for control systems, lighting, and other components in 24V industrial setups. Built-In Protection Functions The Victron Orion 24/12-40A DC-DC converter incorporates essential safeguards to ensure reliable and safe operation. These include protection against undervoltage shutdown, overload, short-circuit, and thermal safeguards. The unit also features temperature-controlled fan-assisted cooling to prevent overheating during continuous high-current operation. Common Questions Is this converter galvanically isolated? No, the Victron Orion 24/12-40A is a non-isolated DC-DC converter, meaning the input and output negative terminals are common. Can I use this to charge a 12V battery? While its fixed 13.2V output is suitable for maintaining a 12V battery bank, this model is primarily a converter for powering 12V loads and is not a multi-stage battery charger. Can multiple units be connected in parallel for higher current? No, this specific Victron Orion 24/12-40A model is not designed for parallel connection to increase output current. What is the purpose of the remote on/off connector? The remote on/off connector allows the converter to be switched on or off using a low-power switch or an engine run/stop signal, eliminating the need for a high-current switch in the input wiring. Installation Notes Ensure the input voltage from your 24V source is within the specified range of 18-35V DC. As a non-isolated converter, ensure the input and output negative terminals are on a common ground in your system. Protect the positive input with an appropriately rated fuse. Refer to the Victron manual for recommended fuse sizes. Connect the DC wiring using the supplied double Faston tabs (6.3mm) for secure connections. Mount the converter in a protected indoor environment with adequate ventilation, as it has an IP20 rating. Utilise the remote on/off feature for convenient system control, connecting it to a low-power switch or engine control. Before You Buy Verify that your input power source is a 24V DC system. This converter is not suitable for 12V input. Confirm that a fixed 13.2V DC output is suitable for your intended 12V loads or battery maintenance requirements. Note that this model is non-isolated; ensure your system design accounts for a common negative ground. This converter cannot be paralleled to increase output current. If higher current is needed, consider a different model or solution. Ensure the installation location provides protection from dust and moisture, consistent with the IP20 rating. All specifications are based on manufacturer data and verified information. Always consult the official Victron Energy manual for detailed installation and safety guidelines. This product comes with a 5-year manufacturer's warranty.
