115V medium frequency static power supply deviceIt is a high-quality AC power supply used to provide start-up, inspection, or maintenance power to aircraft and onboard equipment. It is a necessary ground support equipment for civil airports and airports.

The 400Hz ground frequency conversion power supply converts 50 Hz mains power into a 400Hz, 115/200V three-phase AC power supply, which is used for powering aircraft and onboard equipment. It is a necessary ground support equipment for military and civilian airports, aircraft maintenance bases, aircraft manufacturing plants, and research institutes. According to user requirements, we can produce 0.5kVA-180kVA static power supplies. The adjustment of voltage amplitude adopts advanced technology of space vector pulse width modulation (SPWM), which enables the inverter power supply to maintain small harmonic content and good dynamic performance even when the output load and input power supply change.  

The aviation intermediate frequency static power supply is a mechanical and electrical product that we independently research, design, and manufacture, and has advanced levels in the contemporary world. It outputs a three-phase AC intermediate frequency power supply with a rated frequency of 400Hz and a rated voltage of 115/200V, which can be used as ground support power for various civilian and military aircraft with AC power supply systems, as well as experimental power for aircraft manufacturing plants, maintenance plants, test flight stations, and research institutes. It can be widely used in places with AC power supply such as hangars, aprons, boarding bridges, electronic workshops, laboratories, etc. It has the advantages of good waveform quality, small size, light weight, low noise, no pollution, and low operating costs. Fixed, bridge mounted, and trailer mounted units can be provided according to user requirements.
