Data Center UPS Systems and Power Distribution (APC / Eaton)

Uninterruptible power supply (UPS) systems providing battery-backed power conditioning for data centers, server rooms, and critical IT infrastructure. Range from 300VA tower units for individual servers to multi-megawatt modular UPS for hyperscale data centers. Also includes rack PDUs (power distribution units) for in-rack power management. Dominant suppliers: APC by Schneider Electric (Smart-UPS, Symmetra, Galaxy series), Eaton (9PX, 93PM series), Vertiv (formerly Emerson Network Power). As AI GPU cluster power density increases to 30-100+ kW/rack, UPS and PDU hardware is being stressed beyond legacy specifications.
