The 400HZ static frequency power supply is supplied through the ground wells/terminal cabinets on the apron (hangar), meeting the electrical needs for aircraft maintenance and repair as well as for aircraft starting in the aviation sector. It can also serve as a portable ground power supply for airports, with installation options including fixed, bridge-mounted, and trailer-mounted power supplies.
The 400Hz/200V three-phase AC power supply for ground use, designed for powering aircraft and onboard equipment, is an essential ground support equipment for civil airports, aircraft maintenance bases, aircraft manufacturing plants, and research institutions. Units ranging from 7.5kVA to 180kVA can be produced according to customer specifications.
The voltage amplitude adjustment employs advanced Space Vector Pulse Width Modulation (SV-PWM) technology, ensuring minimal harmonic content and excellent dynamic performance for the static variable power supply even when the output load and input power change. Fixed, bridge-mounted, and trailer-mounted units can be provided according to customer requirements.
The 400Hz intermediate frequency power supply is specifically designed for aviation applications. It is suitable for aircraft and on-board equipment, radar, navigation, and other electronic devices that require a 400Hz intermediate frequency power supply.
The 400Hz power supply, centered around a 16-bit microcontroller and utilizing power electronic devices as the power output unit, incorporates new technologies and modular structures such as digital frequency division, phase locking, waveform instantaneous value feedback, SPWM pulse width modulation, and IGBT output. It boasts strong load adaptability, high efficiency, excellent stability, high-quality output waveform, simple operation, compact size, lightweight, intelligent control, abnormal protection function, adjustable output frequency, fast output response speed, strong overload capacity, fully isolated output, and long lifespan resistance to damage.
