Key Features

Ferro-resonant UPS design

2,200 W load capacity

Protect workloads that cannot tolerate poor power quality. The Eaton FERRUPS 3.1 kVA Tower UPS delivers 3,100 VA / 2,200 W of capacity in a tower form factor, with 14 minutes of full-load runtime to bridge short outages and controlled shutdown windows. Its ferro-resonant design is built to regulate output voltage continuously, helping shield sensitive equipment from unstable input and harmful harmonic currents. This model is well suited to infrastructure teams that need more than basic battery backup. The included diagnostics support automatic startup and scheduled testing of the logic board, battery, and other critical systems, while the regulated output helps preserve battery charge during normal operation. For facilities that depend on consistent power quality, that means fewer surprises and a more controlled response to disturbances. With 120 V AC input and output, plus 2 x NEMA 5-20R and 2 x NEMA L5-30R receptacles, the unit fits established North American deployments. It is a serious choice for teams protecting communications gear, control systems, and other essential loads where downtime carries real cost.
