MPN #: 3S550IEC
Never lose a document or a video call because the lights blink. The Eaton 3S 550 IEC UPS, 0.55 kVA, 330 W, Mini Tower, Black keeps your computer, router and small office gear running when the grid drops. It protects against sudden outages, voltage spikes and noisy power that can damage electronics. If you work from home or run a small office, this unit stops data loss and equipment failure.
Power interruptions are a real headache for anyone who relies on a PC or a network. A sudden loss can corrupt files, interrupt meetings and cause costly downtime. The Eaton UPS solves this by giving you a few minutes of clean power and by filtering out surges that travel through the phone and Ethernet lines. With a compact mini-tower design it fits on a desk or on a wall, so you get protection without clutter.
Use the UPS on a home office desk to keep your laptop, external hard drive and Wi-Fi router alive during brief outages. In a small business, connect the unit to a point-of-sale computer, a network switch and a VoIP phone so customers never experience a dropped call. It also works well in a study room to protect a desktop PC and a monitor while you write papers or edit photos. The wall-mount option is handy in tight cubicles where floor space is limited.
