APS 200

The APS 200 is a stationary solid-state frequency converter engineered to provide 400 Hz electrical power to parked aircraft. Developed in Denmark by ITW GSE, it incorporates the engineering heritage of the AXA Power brand. The unit functions by converting standard utility mains power into the specific frequency required by aircraft electronic systems, allowing operators to shut down the aircraft auxiliary power unit. This transition reduces fuel consumption, noise levels, and carbon emissions during ground turnarounds. This system is typically purchased by airport authorities, ground handling providers, and aircraft maintenance, repair, and overhaul organisations. It is commonly installed on passenger boarding bridges or at fixed apron stands. The unit has been utilised to support a wide variety of narrow-body and wide-body airframes from major manufacturers. While it was a primary infrastructure solution for several decades, the manufacturer has transitioned its production focus toward more recent modular series, moving the APS 200 into a legacy support category. As this model is no longer the current production standard, buyers should approach acquisitions through the secondary market or for spare parts harvesting. The desk suggests verifying the specific internal hardware revision, as components were updated over the product's lifespan. Particular attention should be paid to the condition of the capacitor banks and cooling assemblies, which are vital for voltage stability. Reliability in high-temperature environments depends heavily on the maintenance history of these thermal management systems.
