The S400 is a compact solid-state GPU designed to deliver consistent 400Hz power supporting flexible installations. It is widely applicable to both remote and contact stands, as well as bridge-mounted installations.

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

What is LVRTech and How Does It Work?
LVRTech enables the system to ride through short-term voltage dips without interruption. For example, when the load power is less than 50 kW and the input voltage drops to 40% (input voltage at 160 V), the unit can continue operating for 2 seconds, significantly outperforming traditional solutions. This capability not only protects connected equipment but also provides a critical window for maintenance intervention.

High scalability
Supports diverse installations, widely applicable to contact/remote stands, and adaptable across mobile/-fixed, floor-mounted, and bridge-mounted setups.
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.
