I would buy and recommend this product again!


This product will be used to protect switches in a small network cabinet



Smart Pro 1U Good Choice for small data racks/cabinets


We purchased 7 of these units for the data racks spread throughout the campus. They are prefect for the one or two devices in the racks. The relatively short depth of the units allows for flexibility as some of the racks have limited depth.



so far so good...


I've just installed the unit and so far it seems to work as expected. I haven't had the opportunity to test the batteries or how long it will support the current load, but it mounted in my wall mount rack easily and seems sturdy. I'm disappointed at the lack of platform support for the Power Alert Local software; only Fedora 8 or OpenSUSE 11 in the linux realm. having CentOS/RHEL 6/7 packages would be preferable or at the very least being able to install from source would be acceptable. As it stands now, I'm unable to trigger a proper OS shutdown when the UPS goes on battery or gets to low battery threshold.

What happened???


I've installed these for a number of years as a decent, budget-friendly UPS for network components. Of the last 5 units I've installed, 4 have been defective (so far)...I'm not holding out much hope for the 5th. A UPS should be the most reliable part of your setup - this one is far from it. I can, unfortunately, not rely on Tripp-Lite anymore and have had to switch to another (more expensive) brand. Perhaps you do just get what you pay for, but these experiences have soured me to any Tripp-Lite product. If you can't build a working product at this price point - don't.

Smart pro backup


One of the best back up units to use. Software and setup is easy. Unit is super quiet and mounts onto any rack. Will buy another unit in the future.


Santa Fe NM


Yes, I would buy this product again


We have 7 TV's on our boat and there is a Tripp Ilte hooked up to each one. Once you set them up the first time there is nothing else to do. The unit seamlessly runs our equipment when switching from shore to generator power w/o interruption. I did need help with one question and the help line solved my question quickly. I would never be without one.


Red Bank NJ


We will keep purchasing and selling this product


The customer service was great when we had a faulty unit. The sent us a new one as soon as defect was figured out.




Great low profile & rack mountable UPS.


I have stopped buying other brands of UPS product. This stuff always works. Priced well. Plenty of options. This is a great space saver in your rack.
