Tripp Lite SmartOnLine E-series SU5000RT4UHV is rated2.00 out of5 by2.
Rated 5 out of 5 byGarrett from Battery Replacement is a NightmareAs part of a UPS battery replacement project that I am doing for my employer, I replaced the batteries in seven of these particular UPS units over the past few months. There were three consistent problems that I saw:1. The screws that hold the front plate and the battery bracket in place are very soft and strip way too easily. Some of the screws on our units were so stripped that I had to drill them out with a drill bit in order to remove them. This is unacceptable, given the low cost of quality screws.2. The bottom front edge of the case has a raised lip that is fairly sharp. It is very easy for cables to rub on this lip, especially during battery removal and insertion, potentially causing damage to the cables. I saw evidence of this kind of damage on at least one of our units.3. Lastly, and most serious, on more than half of the devices that I serviced, the old batteries were so stuck inside the case that it required significant time and force to remove them. This is absolutely unacceptable, especially on units with purportedly hot-swappable batteries. The center battery pack comes with a very flimsy paper tab that is supposed to aid in removal, but this tab tore completely almost immediately on most of my units. After that tab is gone, how exactly are the old batteries supposed to be safely removed? As far as I could tell, the manual doesn't even cover this situation.Because of these issues, I cannot recommend this unit and will make sure that my company doesn't purchase any more for future needs.

Rated 5 out of 5 bySTM_Jon from I would buy this againThis is used to provide protection for a pneumatically driven Gifford-McMahon refrigeration cycle cryocooler, a helium compressor, and the water-cooling unit for the compressor. All told a 2.6 kVA constant load, with a 5.3 kVA inductive load. This UPS allows us to conduct research at ~9 kelvin for extended periods without having to worry about a 5% change in voltage turning off the cooling mechanism.
