Minuteman ETR550LG Line-interactive Mini Tower UPS 550VA/330W 8-Outlet

Protect critical security, surveillance and network systems from downtime with the Minuteman ETR550LG line-interactive mini tower UPS. Designed for small to medium loads, this Minuteman UPS delivers 550VA / 330W of dependable backup and features Automatic Voltage Regulation (AVR) to correct brownouts and over-voltages without draining battery life. The ETR550LG supplies eight NEMA 5-15R outlets—separating battery-backed and surge-only receptacles—so you can keep DVRs, NVRs, switches and VoIP phones running while non-critical accessories remain protected from spikes.

Built for IT and security environments, the compact mini-tower fits neatly into rack-adjacent spaces, AV cabinets and security closets. Integrated RJ45 and coax protection defends data and camera lines, and the hot-swappable, replaceable battery reduces field service time and total cost of ownership. ENERGY STAR and RoHS certifications help lower operating costs while meeting environmental standards. Backed by a three-year electronics warranty and connected equipment guarantee, the ETR550LG is an ideal choice for CCTV monitoring, network edge devices and small server protection.
