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.

Questions about this item

What are the dimensions and weight for desktop or wall mounting?

The unit measures 3.10 inches high by 10.80 inches wide by 5.70 inches deep and weighs 5.00 lbs.

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

Plug the included USB cable into the UPS USB port and your PC, then install the management software so the system can trigger a safe shutdown during an outage.

When will the internal battery need replacing?

The valve-regulated lead-acid battery typically lasts three to five years; replace it when runtime drops well below the rated 5.6 minutes at 150 watts or the unit signals a battery fault.
