Eaton Tripp Lite OMNI900LCD Tower UPS AVR LCD 900VA 475W

If you want a simple, dependable UPS for a home office or media setup, the Eaton Tripp Lite OmniSmart OMNI900LCD is built for exactly that job. It is a 120V, 900VA 475W line interactive tower UPS that handles the most common power problems, blackouts, brownouts, and surges, while giving you enough battery runtime to save work, avoid corrupted files, and prevent annoying resets of your entertainment gear.

AVR is the big value feature in real life. When the utility voltage sags, AVR regulates brownouts as low as 89V back to usable levels without switching to battery. That reduces battery wear and keeps your equipment stable. It is also efficient in normal operation, with a 97% line mode efficiency rating, so it wastes less energy and puts out less heat.

Outlet layout is practical for mixed setups. You get eight outlets total, four battery supported plus surge protected for the devices that must stay on, and four surge only outlets for gear that does not need battery runtime. That makes it easy to protect a PC, monitor, router, and NAS, while still surge protecting speakers, a TV, or other accessories.

Runtime depends on your load, but this model is aimed at lighter loads where it can really stretch. It can support entry level PCs for up to 50 minutes in a blackout, and it can keep single A V components running for much longer. For reference, it provides about 3 minutes at full load and about 10 minutes at half load, which is plenty for safe shutdown in many typical home office scenarios.

The LCD on the front is actually useful, not just decorative. It shows line power status, battery status, low battery or replace warnings, and voltage boost operation. The screen can rotate for easy viewing in different placements, and the dimmer helps if it is in a bedroom, living room, or office where you do not want a bright display.

For shutdown automation, the USB port supports unattended shutdown, and the HID compliant USB interface works with the built in power management features in Windows and macOS. You can also use PowerAlert software if you want more control. Bottom line, it helps you shut down cleanly instead of losing data or damaging drives from abrupt power loss.

Benefits
You protect your PC and home entertainment setup from outages and voltage drops without constant battery cycling. You keep important devices powered long enough to save and shut down safely. You also reduce the risk of lost recordings, device resets, and corrupted files. Setup stays clean because you can choose which devices get battery support versus surge only protection.

1. How many outlets are battery backed vs surge only?
   It includes 8 outlets total, 4 are battery supported and surge protected, and 4 are surge protection only.
   
2. Will it work with Windows and macOS automatic shutdown?
   Yes. The USB interface is HID compliant, so it can integrate with built in power management and auto shutdown features on both Windows and macOS.
   
3. What kind of runtime should I expect?
   It depends on your connected wattage. It can run lighter loads for a long time, up to about 50 minutes for an entry level PC, and roughly 10 minutes at half load or about 3 minutes at full load.
