Application notes
Online double conversion regenerates every cycle, so loads see clean power through sags, surges and generator transfer. The P91-1000 is a common pick for network closets, server and storage racks, AV systems and multi-site retail or education deployments. Runtime comes from the internal battery only, so size it for ride-through and controlled shutdown.
