Compact line-interactive UPS for home office

The Minuteman ETR550LG is a 550VA 330W line-interactive UPS designed for desktop computers, networking gear and peripherals in a 120V environment. It provides battery-backed power to four NEMA 5-15R outlets while four additional outlets deliver surge-only protection. A six-foot NEMA 5-15P cord connects to the wall.

Output voltage window and runtime limits

The unit regulates output between 104VAC and 140VAC while accepting input from 90VAC to 140VAC at 60Hz. At full 330W load the battery lasts 3.9 minutes; at half load it extends to 13.7 minutes. This runtime suits safe shutdown rather than extended operation. The 1200 joule surge rating and built-in circuit breaker protect connected equipment from transients.

Mini-tower form with replaceable battery

The mini-tower chassis measures 11.4 by 3.9 by 11.0 inches and operates from 32°F to 104°F in non-condensing humidity up to 95 percent. Battery alarms and a silencer give audible status without software. The BM0063 battery is user-replaceable, extending service life. Approvals include cTUVus to UL1778, CSA 22.2, FCC Part 15, CE and Energy Star 2.0.

Questions about this item

Should I pick a UPS with more VA or more outlets for my setup?

This model provides 550 VA and 330 W across ten outlets — four with battery backup and four surge-only — so you choose based on how many devices need runtime versus only surge protection.

What does the 330 W rating mean when my PC and monitor are plugged in?

It is the maximum real power the unit can deliver on battery; if your combined load stays at or below 330 W the UPS will keep them running for about 3.9 minutes at full load or 13.7 minutes at half load.

How does the NEMA 5-15 input and output limit what I can connect?

The 5-15P plug and 5-15R receptacles restrict you to standard 120 V North American cords rated for 15 A, capping total connected equipment at the UPS’s 550 VA / 330 W rating.
