Eaton INTERNET550U – Compact Standby UPS for PC

Product Overview

The Eaton INTERNET550U is a 550VA/300W standby UPS built to protect a PC and its peripherals from data loss and downtime during brownouts and blackouts. This compact standby UPS for PC and small workstation deployments packs eight total outlets, two of which are widely spaced for large transformer plugs, into an ultra-compact desktop chassis. Four outlets provide full battery backup and surge suppression for a computer and monitor, while four surge-only outlets cover printers and other accessories that don't need runtime support. A HID-compliant USB interface enables integration with standard operating system power management, making this small business UPS battery backup a straightforward add to a single workstation or light-duty network closet.

Product Description

At 4.13 in H x 4.33 in W x 7.28 in D and under 5 lb, the INTERNET550U fits on a desk, under a monitor, or on a shelf in a small network closet without consuming significant footprint. Standby topology switches to battery within a typical 6ms transfer time when utility power drops, delivering roughly 1.2 minutes of runtime at full 300W load or 5 minutes at half load, enough time for a connected PC to save open work and shut down cleanly. Single-line phone/DSL or Ethernet dataline suppression protects a modem or router from surges arriving over the communication line, a common failure point for workstations sharing a rack with basic network gear. The HID-compliant USB interface works with standard power management software to trigger an automatic, orderly shutdown sequence during an extended outage. Four of the eight outlets provide full battery backup and 316 joules of surge suppression, while the remaining four are surge-protected only, letting an installer route battery support to the PC and monitor while accessories like a printer draw from surge-only outlets. With greater than 98% efficiency in line mode and a 3-year limited warranty, the INTERNET550U is a cost-effective option for protecting individual workstations, point-of-sale terminals, or small network appliances against short outages.
