MPN #: 3S550I
Imagine your home office losing power right when you are saving an important document. The Eaton 3S550I Standby UPS 0.55 kVA 330 W with 8 C13 Outlets is a compact battery backup that keeps your devices running for a short time and protects them from voltage spikes. Without a UPS, a sudden outage can cause data loss, hardware damage, and missed deadlines. This unit gives you the peace of mind you need to keep work and entertainment devices safe.
Power cuts and surges are common in many homes and small offices. When the grid fails, computers, routers, and monitors shut down instantly, which can corrupt files and interrupt internet connections. This problem matters because it directly affects productivity and can cost money to replace damaged equipment. The Eaton UPS detects a loss of voltage, switches to its internal battery in less than a second, and supplies clean, stable power to up to eight devices through C13 outlets. It also filters spikes so your electronics stay safe.
The UPS fits on a desk, a shelf, or a small server rack. Use it to protect a desktop PC, a laptop charger, a Wi-Fi router, a network switch, a printer, or a home media player. It is ideal for remote workers who need uninterrupted internet, for gamers who cannot lose a match, and for small businesses that run point-of-sale terminals. The eight C13 outlets let you plug several devices at once, so you can keep your whole work-station powered during a brief outage.
