I have been using Tripp-Lite UPS power backups for 30 years and they have never failed me. I bought the SmartPro LCD UPS because of the power line conditioning. The UPS is the first line of defense for power failures, but when you have power surges or power line dips the SmartPro takes care of this by using the buck/boost features. Computer circuits do not work well when the power dips below 100 VAC or when it surges over 125 VAC. The SmartPro LCD corrects these problems so your computing is safe and you don't even have to think about it ... it just works. Day & Night, 24/7 all year long. It's a Tripp-LIte and it works!
I bought two of these units to use as backup power supplies for two Dell rack mount servers. These UPSs work great and the optional software to monitor the UPS devices. I will be buying either other units like these in the future or other products from Tripplite.
Purchased it during hurican season in florida. Have regular brown outs in my location. I heard it click on when necessary and I haven't had any computer restarts or modem issues since I turned it on. The unit smells toxic out of the box. Plugging it in only makes matters worse. I was doubtful but people said the smell dissipated over time. Took no less than 7 days, but sure enough the smell has gone away and i can keep it about 2 feet away from me with no ill effects. I recommend running it for a week in an open environment.
Use it to protect my home entertainment system. We have frequent voltage drops (brownouts) and momentary power outages. This is dangerous to electronic equipment and is inconvenient when it causes my TiVo to reboot (which takes several minutes to come back up). This UPS handles those problems admirably. I also like the ability to see the load utilization on the front display.
