AXA Power - An ITW GSE Group Company

One Plug - One GPU

AXA Power strongly recommends the idea of "One Plug — One GPU." Since the max power that an aircraft plug can transfer is 90 kVA, it makes sense to let this criteria determine the rating of the GPU. One may not always be able to exploit the total GPU power at the time of installation, but with the ever increasing power requirements of modern aircraft, it is almost certain that full power will be required after a few years. Of course, it goes without saying, that for power requirements above 90 kVA, i.e. 180; 270 and 360 another GPU is simply added.

The "One Plug — One GPU" goes hand in hand with AXA's intelligent Plug & Play system — a unique and revolutionary way of compensating for voltage drop in distribution cables. The Plug & Play facility surpasses the traditional compensation systems, where the voltage is regulated as a function of the average output current or where the system relies on a voltage feed-back from the plug.

Within miliseconds, the patented Plug & Play system automatically identifies all relevant cable parameters to determine the voltage drop whereafter it controls each phase individually as a function of any load characteristic thus securing the optimum voltage quality at the aircraft plug.
The result is an extremely high-voltage quality at the plug — both for traditional power factor 0.8 aircraft and the new power factor 1 aircraft.
