28V Power Supply Vehicle

The DC28.5V aviation DC power supply vehicle adopts soft-switching and PWM controlled full-bridge conversion technology, utilizing inverter technology to convert 50Hz industrial frequency power into aviation 28V DC for starting tanks and aircraft, as well as for power-on inspections of airborne equipment. The product employs PWM inverter technology and an intelligent control system, using reliable industrial standard components, and is strictly produced in accordance with the GJB9001B quality system, ensuring high-performance indicators and high 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 small size, light weight, 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.
