AERO JetGo 300 28V DC Diesel Hybrid Ground Power Unit


Powered by a 3-cylinder, water-cooled Kubota diesel engine (fully Tier IV compliant, No DEF required), the JetGo 300 is designed to provide continuous power for avionics and to start the engines on all DC turbine and turboprop aircraft. JetGo 300 users benefit from a compact unit, user friendly controls and very low operating costs, with the further advantage of low dBA signature and reduced CO2 emissions. Normally, a diesel GPU four times the size of the JetGo 300 is necessary to deliver the peak amperage for starting large turbines.

***The quoted figures are the theoretical instant short circuit current across the battery terminals. The maximum amperage that will be delivered by the GPU to the aircraft’s external power connection is significantly reduced due to cable length, cable size and duration of power. These figures are quoted for comparison purposes only. † If using Jet A1, JP8 or similar, some loss of power will occur compared to diesel due to jet fuel’s lower calorific value.
