What is the maximum voltage allowed in the DC electrical system?

In the DC electrical system of aircraft like the Dassault Falcon 7X, the maximum voltage is typically defined by the aircraft's system design specifications to ensure safety and reliability across various components and systems. The maximum voltage allowed of 32 volts is significant because it provides a balance between delivering adequate power for operational needs while also ensuring that the electrical components can handle the voltage without risk of damage or failure.

The 32-volt limit is important when considering the operational characteristics of the aircraft's systems, including avionics, lighting, and other electrical devices. Operating above this voltage can introduce risks such as overheating and increased wear on components, which could lead to electrical failures or reduced lifespan of systems. Moreover, adhering to this limit helps maintain compatibility with standard aircraft components designed for similar voltage specifications, ensuring a level of interoperability and safety within the electrical system.

Other voltage options, such as 28, 30, and 34 volts, do not align with the design criteria established for the Falcon 7X's DC electrical system. Maintaining a voltage of 32 volts is critical in achieving reliable performance while also aligning with aviation safety standards.
