Ultra-Compact UPS for Home and Office

The INTERNET550U is a 550 VA standby uninterruptible power supply rated at 300 W. It provides battery-backed power to four outlets and surge protection to four more. A USB port and TEL/DSL line protection are included for equipment management and data-line safety. The unit is designed for desktop or wall mounting.

Replaces Basic Surge Strips for Critical Devices

This UPS upgrades a simple power strip by adding battery runtime during blackouts and brownouts. The jump is worth it when you need minutes to save files and shut down a PC, home-theater component or digital-signage player safely. It is not suited for loads exceeding 300 W or for installations requiring pure sine-wave output.

Simple Desktop or Wall Installation

The tower form factor measures 3.10 by 10.80 by 5.70 inches and weighs 5.00 lbs. Plug the NEMA 5-15P cord into a 120 V branch circuit and connect equipment to the ten NEMA 5-15R outlets. Common issues include mistaking surge-only outlets for battery-backed ones and forgetting to connect the USB cable for automatic shutdown software.

How do I connect the UPS to my computer for shutdown software?
