Eaton Tripp Lite AVR550U 550VA Line-Interactive Desktop UPS

The Eaton Tripp Lite AVR550U is a compact 550VA/300W line-interactive UPS that provides reliable battery backup, automatic voltage regulation (AVR), and surge protection for electronics in your race timing setup, home office, media center, or digital signage system. With eight NEMA 5-15R outlets, four with full battery backup and AVR and four with surge-only protection, it shields devices like readers, computers, routers, printers, and consoles from blackouts, brownouts, voltage fluctuations, and power spikes. A 316-joule surge suppression rating and built-in EMI/RFI filtering help prevent performance issues caused by electrical noise. Operating at greater than 95% efficiency, it also helps reduce energy usage and heat output.

In the event of a power outage, the AVR550U delivers enough backup power to save work and safely shut down your system, offering up to 32 minutes of runtime for energy-efficient setups. The included USB port connects to PowerAlert software, enabling unattended safe system shutdowns when power is lost. A quiet design ensures the alarm sounds only when necessary, while dual front-panel LEDs provide clear status updates. Its space-saving housing fits easily on a desk or mounts to a wall using integrated keyhole slots. Backed by a 3-year warranty and $100,000 connected equipment insurance, this UPS offers dependable power protection with enhanced voltage regulation.
