UPS/SST debate: timing mismatch, not binary disruption

Investors have expressed concern that 800VDC could eliminate portions of

centralized low-voltage UPS architecture, but SSTs do not need to be broadly

commercialized for that transition to begin. SSTs remain nascent in data center

applications, while early 800VDC deployments are more likely to rely on sidecars,

conventional rectification, MV UPS, BESS, and DC-coupled storage. We would

expect UPS to face gradual disintermediation over a long timeline rather than
