ITW 1400: 28.5 VDC Mains Powered Portable GPU

The ITW GSE 1400 is a small, light and easy maneuverable solid-state GPU that does not take up much space neither in mobile nor in the fixed version. This unit is ideal for all DC powered commercial aircraft operating on a ramp or in a hangar.

ITW 2400: Compact Mains Powered GPU

The world's most Unique GPU provides

  • 400% Overload
  • Unique Voltage Quality
  • Clean Input Power

The 2400 compact GPU is the safe choice for the supply of modern aircraft. As the only GPU in the market, it has 400% overload at output! Also, it provides 90 kW continuous at an ambient temperature of 56℃.

The AXA 2400 Compact is equipped with the patented Plug & Play system. Therefore, you experience an outstanding voltage quality at the aircraft plug. This is what matters and what makes your aircraft accept the voltage from the GPU.

The Plug & Play means that the AXA 2400 Compact fulfils the stringent requirements of most installations as it compensates for long symmetrical output cables, unbalanced loads as well as various power factors.

The magnetic wave-shaping topology ensures a clean input power with a unity power factor and a current THD less than 5%.
