Eaton Internet350U ? Standby UPS 350?VA/180?W

Overview

The Internet350U by Tripp Lite (an Eaton brand) is a compact standby uninterruptible power supply (UPS) designed to deliver battery?derived AC support during short power interruptions and voltage disturbances. IT technicians and infrastructure teams deploy this unit where basic continuity is required to save work and safely shut down equipment?not for extended runtime or high?availability systems.

This UPS provides 350?VA / 180?W capacity with a single?phase 120?V AC output and six NEMA 5?15R outlets (three battery?supported and three surge?only). Protection includes brownout/blackout coverage plus TEL/DSL line surge suppression via RJ11 jacks. The standby/offline topology switches to battery power when input voltage falls outside acceptable thresholds.

The ultra?compact design fits on desktops, shelves, or wall mounts in branch offices, small workstations, or home labs where space is limited and only short hold?up time is needed. A USB port enables integration with host systems for unattended shutdown using Tripp Lite?s PowerAlert software.

Interface and status components include front LEDs for line/battery state and audible alarms for low battery or fault conditions. Typical runtime is on the order of a few minutes at full load?sufficient only to initiate orderly shutdown or maintain critical network equipment during brief outages.

Avoid using this model where high availability or longer runtime is required (e.g., servers, SAN/storage arrays), as its standby topology and modest capacity are not sized for sustained loads.
