The DC 28.5V aviation DC power supply vehicle adopts soft-switching and PWM-controlled full-bridge conversion technology. It utilizes inverter technology to convert 50Hz industrial frequency power into aviation 28V DC, providing power for the startup of combat vehicles and aircraft, as well as for the electrical inspection of airborne equipment. The product employs PWM inverter technology and an intelligent control system, using reliable industrial standard components and strictly following the GJB9001B quality system for production, ensuring high-performance indicators and reliability. It can be provided as a self-generating or power-supply type vehicle based on user requirements. It features fast dynamic response, strong overcurrent capability, and low output ripple. Advantages include compact size, lightweight design, low noise, high efficiency, and simple operation. The 28V aviation ground power vehicle supplies power directly to aircraft via cables from the apron (hangar), meeting the electrical requirements for aircraft inspection and maintenance. It is widely used in aerospace, ground radar stations, ships, submarines, computer stations, military precision instruments, and imported equipment power supply systems.
