Eaton internet550u Standby Ups 550VA 300W 8-outlet

Product Description

The EATON internet550u is an ultra-compact standby uninterruptible power supply rated at 550VA and 300 watts, designed to protect PCs, network workstations, and serial-monitored equipment from power interruptions. The unit maintains AC output during blackouts and brownouts, with brownout ride-through beginning at 99 volts. It includes a DB9 serial monitoring port with cabling for unattended system shutdown through a simple serial communications interface. Installation is straightforward for IT and low-voltage technicians managing small office or workstation-level power protection deployments.

This UPS is suited for residential and light commercial environments where network workstations, small servers, or serial-port-dependent systems require continuous power availability. The wall-mountable form factor keeps it off the floor or desk surface in space-constrained installations. With eight outlets total, it supports multiple connected devices simultaneously. TEL/DSL line surge suppression provides additional protection for modem and phone line connections running through the same installation point.

Installation Notes

Installation is typically performed by IT technicians or low-voltage electricians. Before connecting or disconnecting load equipment, power down all attached devices and verify the UPS battery is discharged to a safe level. Wall-mounting should use hardware appropriate for the wall construction type and rated for the unit weight. Verify local electrical codes and outlet ratings before connecting the UPS to branch circuit wiring.
