Electric ground power unit S400-A

fixedmobilebridge-mounted

The S400-A briege-mounted GPU integrates a solid-state ground power unit with an automatic 28-meter cable coiling device into a compact, all-in-one system — ideal for boarding bridge installations.

At the heart of the S400-A lies AEME’s independently developed voltage stability solution LVRTech (Low-Voltage Ride-Through). This technology is engineered to maintain voltage stability and ensure reliable power delivery.

What is LVRTech and How Does It Work?
LVRTech enables the system to ride through short-term voltage dips without interruption. When the load power is below 50 kW and the input voltage dips by 60% (input voltage 160 V), the unit can continue operating for 2 seconds. This capability not only protects connected equipment but also provides a critical window for maintenance intervention.

Flexible Installation & Easy Maintenance
Compact, modular architecture enables flexible deployment and simplifies maintenance and operations.
Comprehensive Protection
Includes over/under voltage, overcurrent 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.
High scalability
Supports diverse installations, widely applicable to contact/remote stands, and adaptable across mobile/-fixed, floor-mounted, and bridge-mounted setups.

Equipped with 25m or 28m automatic cable reels, it can be set up either bridge-mounted, ground-mounted, or mobile, depending on operational requirements.
