Eaton 5SC500 - Tower UPS 500 VA/350 W
Overview
The Eaton 5SC500 is a line-interactive uninterruptible power supply (UPS) designed to provide basic power continuity and voltage regulation for small IT equipment, networking gear, and office systems on 120 V AC mains. It is deployed by IT support teams, facilities engineers, and small business administrators to prevent unexpected shutdowns and data loss during brief utility power interruptions, brownouts, and surges.
Rated at 500 VA (350 W), this unit uses line-interactive topology with automatic voltage regulation (AVR) to support sensitive electronics across typical input voltage variations without unnecessary battery use. Output is delivered via four NEMA 5-15R receptacles, while input is through a NEMA 5-15P plug and 6 ft power cord. Standard communications include both USB (HID) and RS-232 (RJ45) interfaces for monitoring and orderly shutdown support.
The 5SC500 is configured in a compact tower form factor (~8.2″ H × 5.9″ W × 9.4″ D), suitable for placement on shelves or under desks in server rooms, branch closets, or office environments where rackmount space is unavailable or unnecessary. An LCD status display provides real-time metrics including load, battery level, and power events for on-site diagnostics.
Battery management uses Eaton's ABM 3-stage charging technology to extend service life and warn of battery replacement needs. The internal sealed lead-acid battery is user-replaceable but not hot-swappable, and the unit does not support external battery extensions. Runtime is sufficient to bridge short outages or enable orderly shutdowns but not for prolonged power loss events.
In practical deployment, the 5SC500 supports edge devices, small servers, workstations, and communication appliances in low-power IT closets or office environments where brief power continuity is required. It is not suited for core data center or high-availability applications involving heavy load or extended outage duration.
