MODULAR POWER MEETS SILICON CARBIDE:
HOW KEOR FLEX REDEFINES RESILIENCY FOR THE AI-DRIVEN DATA CENTRE
The accelerating demands of AI and high-density workloads are fundamentally shifting the data centre’ s baseline for TCO and sustainability. As Pierre ECUYER, Center of Excellence Director – Critical Power, Legrand, observes, this strategic imperative is powered by a convergence of Silicon Carbide( SiC) technology and modular architecture. Legrand’ s Keor FLEX platform leverages SiC for unprecedented efficiency and power density, while its modular design ensures flexible,‘ pay-as-you-grow’ scalability. This award-winning system transforms the UPS into a dynamic, resilient asset essential for addressing unpredictable IT growth, making the adoption of this future-proof strategy critical now. h
How does Silicon Carbide( SiC) integration fundamentally shift the baseline for UPS power density and efficiency, forcing a recalibration of industry TCO and sustainability standards?
Silicon Carbide( SiC) technology is setting new performance standards for Uninterruptible Power Supply( UPS) systems. With its exceptional energy efficiency, compact design and superior thermal resilience, SiC-based architectures are driving a significant shift towards smarter and more sustainable power strategies in data centres.
Thanks to its wide bandgap of 3.26 eV – almost three times that of traditional silicon – SiC operates efficiently at higher voltages, switching frequencies and temperatures. This capability significantly reduces both switching and conduction losses, allowing for online doubleconversion efficiencies of 98 – 99 % while

maintaining consistent performance across a wider range of loads.
Equally transformative is the increase in power density. SiC’ s lower on-state resistance and thinner drift region enable UPS designs that are up to three times smaller than their silicon-based
