ITW GSE Operator Interface

The icon based operator interface is common for all ITW GSE products. It is easy and intuitive and guarantees correct operation.

The operator only has to press the combined start/stop button – nothing more. He can also monitor various parameters such as voltage and current at the display screen. For set-up and maintenance purposes, there is a deeper level dedicated for the technician.

How can our Ground Power Units with 28V help your business?

It goes without saying that an external power supply is more powerful than the onboard battery of the aircraft / helicopter. Therefore, it makes sense to use an external 28 V supply, if available.

The ITW GSE 1400 solid-state GPU is ready to provide power as soon as it is connected to the mains supply and the start button is activated.

What is Ground Power Units like e.g. GPU 28V?

The onboard electrical system of smaller aircraft and helicopters is a 28 VDC voltage.

The aircraft / helicopter can start their engine using the onboard battery, but it may be an advantage to use an external Ground Power Unit to do the job. Find your line powered or battery options below.

ITW GSE supplies green 28 VDC ground power units based on solid-state or battery technology. Also, a diesel driven 28 V unit is available.

Why should you invest in our Ground Power Units such as GPU 28V?

To prolong the lifetime of the onboard aircraft battery or in case the onboard battery is empty, an external 28 V Ground Power Unit – also called a transformer rectifier unit -  is required to start up the engines.
That is much similar to what happens when a car is low on battery.

The ITW GSE 1400 solid-state unit and the ITW GSE 7400 JetEx battery eGPU are both very quiet and emission free which makes them ideal for use, also in hangars.
