The general design rule is that the voltage at the aircraft plug must be
115 V ±3 V.
Nobody knows what the design criterias of the future will be.
Our best guess is that the tolerance will narrow. Therefore, the
AXA2400 Hz ground power units are all provided with the patented Plug & Play facility - a unique and revolutionary way of compensating for voltage drops in distribution cables which provides you with the best possible voltage where it is needed: namely at the aircraft plug ! This goes forboth traditional power factor 0.8 aircraft and new power factor 1 aircraft.
The AXA Plug & Play system automatically identifies all relevant cable parameters to determine the voltage drop and controls each phase individually as a function of any load characteristic.
The AXA Plug & Play feature thereby surpasses the traditional compensation systems, where the voltage is regulated as a function of the average output current or where the system relies on voltage feed-back from the plug.
