Compact 350 VA standby UPS for desktop protection

The Tripp Lite INTERNET350U is a 350 VA, 180 W standby uninterruptible power supply that keeps a computer, router or modem running during brief outages. It provides six NEMA 5-15R outlets, three backed by battery and three surge-only, plus a USB port for HID-compliant monitoring with PowerAlert software. A single RJ-11 line protects telephone or DSL equipment. The unit mounts on a desk or wall and recharges in about four hours.

Suits home offices needing short runtime

This UPS fits users who want battery backup for a single workstation and network gear, with audible alarms for power failure and overload. Buyers who need more than 11.3 minutes at half load, higher wattage for multiple monitors or a laser printer, or extended runtime for servers should look at larger units. The 380 joule surge rating covers modest spikes but not whole-room protection.

Simple plug-and-play setup with wall-mount option

Connect the NEMA 5-15P plug to a 120 V wall outlet, attach devices to the labelled outlets, and link the USB cable to a PC for automatic software detection. The VRLA battery is user-replaceable when runtime degrades. Common issues include forgetting to enable the UPS outlets for critical loads, leaving the USB cable disconnected so alerts do not reach the OS, and exceeding the 180 W limit which triggers the overload alarm.

Questions about this item

What input plug must the wall socket accept for this UPS to connect?

The UPS uses a NEMA 5-15P plug, so the wall socket must be a standard 120 V North American receptacle.

Can devices plugged into the three surge-only outlets keep running during a power cut?

No, only the three UPS battery-supported outlets provide backup power; the surge-only outlets lose power when the mains fails.

How can I confirm the USB management link is active after installing PowerAlert?

PowerAlert will display the UPS status and battery level once the USB cable is connected and the software detects the HID-compliant port.
