Eaton AVR550U – AVR 550VA Mini-Desktop UPS

Product Overview

The Eaton AVR550U is a 550VA line-interactive mini-desktop UPS offering ultra-compact automatic voltage regulation for PCs and workstations. It maintains 120 volt nominal output across an 83 to 147 volt input range, correcting common voltage fluctuations without switching to battery. With four battery/surge-protected outlets and four additional surge-only outlets, it provides focused protection in a smaller footprint than the AVR Series' larger models.

Product Description

This AVR Series UPS shares the same line-interactive, voltage-regulating design as its larger siblings but in a mini-desktop form factor suited to space-constrained workstations. Automatic voltage regulation corrects brownouts and overvoltages in-line, which reduces the frequency of battery transfer events and helps extend both battery and equipment life. Four battery/surge-protected outlets cover the essentials, typically a PC and monitor, while four additional surge-only outlets protect peripherals such as printers or speakers that do not require runtime during an outage. A HID-PDC compliant USB port supports automatic shutdown software, and single-line telephone/DSL surge suppression protects modem and fax lines sharing the same circuit. The space-saving right-angle input plug keeps the unit low-profile against a wall or under a desk, an advantage in compact workstation and small-office layouts. Because it maintains 120 volt output across an 83 to 147 volt input range, the AVR550U is well suited for locations with variable utility power quality. Its smaller outlet count and capacity make it a fit for a single workstation or light-duty equipment rather than multi-device setups. For organizations standardizing on the AVR Series across a mix of workstation sizes, the AVR550U extends that consistency to smaller or secondary desks.
