Never lose your work when the power flickers. The Eaton 3P Ellipse 900 is a compact standby UPS that protects computers, routers and small office equipment from sudden outages. If the grid drops, your devices shut down safely and data stays intact. This unit gives you the peace of mind you need during unpredictable power cuts.

Its stepwise waveform and high efficiency make the transition smooth and quiet.
