Back in the day I used APC power supplies but they started failing rapidly so I switched to Tripp-Lite and had great success for years but like the APC I am noting they are not lasting as long as they used to they just stop working. I use the larger Tripp-Lite in my server racks and have zero issues with them and experience excellent runtime when on battery.
I'm looking to change. My current Tripp-Lite model I am using is the OMNIVS1500 but I want to try something different. Suggestions?
