'S400-A'     Bridge-Mounted Solid-State GPU

The S400-A is a compact solid-state GPU designed to deliver consistent 400Hz power.
It integrates a solid-state ground power unit and the AEME S25 25-meter cable coiling device into an all-in-one system, suitable for boarding bridge installations. The S400-A has been reliably operating at numerous airports across the Asia-Pacific region and has earned recognition as a proven, market-trusted solution.

Power assurance when it matters most

The S400-A solid-state power unit integrates advanced technologies such as LVRTech™ (low-voltage ride-through), space vector pulse width modulation (SVPWM), voltage decoupling control, and dynamic voltage compensation. These features ensure stable voltage output and reliable power delivery even under unbalanced load conditions.

LVRTech™: What It Is and How It Works

LVRTech™ is AEME’s independently developed voltage stability solution. It resists grid voltage dips and interruptions, significantly enhancing the reliability of aircraft power supply. When the power is below 50 kW and the input voltage falls by 60% (input voltage 160 V), the unit can continue operating for up to 2 seconds, delivering reliable performance that surpasses conventional solutions.

The AEME GSE S-Power series also includes other options: S400 floor-mounted solid-state GPU and S400 towed solid-state GPU.
