The S400 is a compact solid-state GPU designed to deliver consistent 400Hz power supporting flexible installations. The S400 (horizontal) can be integrated with our S25 25-meter cable reel and mobile chassis. As a key component of a modular all-in-one system, 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, minimize distortion, 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: In the event of a grid voltage drop to 40%, LVRTech maintains continuous operation for up to 2 seconds under a full 90kW load — significantly outperforming traditional solutions. 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, 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. 1050*580*800(H)/800*580*1450(V) 400(H)/420kg(V)
