115V Medium Frequency Static Power Supply UnitHigh-quality power supply for aviation, designed to provide start-up, inspection, or maintenance power to aircraft and on-board equipment. Essential ground support equipment for civil airports.
The 400Hz ground variable frequency power supply converts 50 Hz municipal power to 400Hz, 115/200V three-phase AC power, used for supplying power to aircraft and on-board equipment. It is an essential ground support equipment for military and civil airports, aircraft maintenance bases, aircraft manufacturing plants, and research institutes. According to customer requirements, static frequency conversion power supplies from 0.5kVA to 180kVA can be produced. The adjustment of voltage amplitude employs advanced space vector pulse width modulation (SPWM) technology, ensuring that the static frequency conversion power supply maintains low harmonic content and good dynamic performance even when the output load and input power change.
Our self-developed, designed, and manufactured airborne medium-frequency static power supply is a state-of-the-art electromechanical product. It outputs a rated frequency of 400Hz and a rated voltage of 115/200V three-phase AC medium-frequency power supply. It can serve as a ground support power supply for various civil and military aircraft with AC power systems, as well as an experimental power supply for aircraft manufacturing plants, maintenance facilities, test flight stations, and research institutes. It is widely used in locations with AC municipal power supply, such as hangars, aprons, boarding bridges, electronic workshops, and laboratories, offering advantages like good waveform quality, compact size, light weight, low noise, non-pollution, and low operating costs. Fixed, bridge-mounted, and trailer-mounted units can be provided according to customer requirements.
