Mobile ground power unit S400-A

bridge-mountedfor aircraft90 kVA

The S400-A integrates a solid-state ground power unit and a 25-meter cable coiling device into an all-in-one system, suitable for boarding bridge installations. Leveraging advanced technologies such as low-voltage ride-through (LVRT), space vector pulse width modulation (SVPWM), voltage decoupling control, and dynamic voltage compensation, the system ensures stable voltage output and low distortion. It continues to deliver reliable power under unbalanced load conditions and effectively protects connected equipment. Modular, smart, and safe Flexible Installation & Easy Maintenance Compact, modular architecture enables flexible deployment and simplifies maintenance and operations. Comprehensive Protection Includes over/under voltage, overcurrent, and frequency protections to ensure safe and reliable operation. Cloud-Based Management Connected to a cloud platform for digital monitoring, full-process diagnostics, and precise fault detection, enhancing overall operational efficiency.
