When the aircraft engine is not operational (such as during ground tests), the main power supply is also inactive, and it is powered by the auxiliary power supply. The aircraft ground power unit or auxiliary power unit (a power system consisting of a small airborne engine, generator, and hydraulic pump, etc.) is a common auxiliary power source. In the event of a main power supply failure during flight, the battery or emergency generator serves as the emergency power supply.
Aircraft-powered electrical equipment demands high-quality power supply, including technical standards for voltage adjustment accuracy, frequency adjustment accuracy, AC voltage waveform sinusoidal purity, voltage surges, and spikes, etc.
Aviation ground power supply equipment reliably manages power systems and batteries through intelligent control. It is compatible with modems and can be remotely monitored centrally via the public or telephone network. Capacity expansion is convenient. The monitoring module also ensures reliable intelligent management of power systems and batteries, with modem compatibility and remote centralized monitoring via the public or telephone network.
