What happens if the voltage supplied by the GPU does not match the aircraft's requirements?

If the voltage supplied by the GPU does not match the aircraft's requirements, serious damage to the aircraft's electrical systems and connected equipment can occur. Supplying a voltage that is too high (overvoltage) can overload and overheat electrical components, potentially causing them to fail or burn out. This can damage sensitive avionics, lighting systems, and other electrical devices. Supplying a voltage that is too low (undervoltage) can result in the malfunction of systems that require a specific voltage to operate correctly. Undervoltage can also cause electrical motors to draw excessive current, leading to overheating and premature failure. In either case, a voltage mismatch can lead to costly repairs, operational delays, and potential safety hazards. Therefore, it is critical to verify that the GPU's voltage output matches the aircraft's voltage requirements before connecting the GPU.
