The Eaton 9PX is an online double-conversion rack/tower UPS. Eaton builds the 9PX from 700VA to 11kVA in 120V, 208V and 120/208V versions, with split-phase models from 6–10kVA, and extended battery modules (EBMs) for longer runtime (eaton.com). Online double conversion means zero transfer time to battery, which Eaton recommends for mission-critical equipment and sites with poor or unreliable utility power.
