AI workloads create highly variable and power-intensive demands that challenge traditional datacenter infrastructure. Vertiv’s testing of the Liebert EXL S1 large UPS demonstrates its ability to deliver stable, Class 1-compliant voltage and frequency across critical scenarios—utility operation, utility-to-generator transitions, and generator operation. The system handled rapid load fluctuations typical of GPU-driven AI training without compromising output stability. With unmatched overload capabilities and resilient design, Vertiv’s large UPS platforms, including Trinergy, ensure power reliability, reduce battery strain, and protect against costly disruptions in AI-driven data centers.
