Since 1922
We have been building power protection since the year the first commercial radio stations went on air, and the catalog on this site is the part of that work you can put on a bench today.
Tripp Lite started in Chicago in 1922, back when a house wired for electricity was still worth remarking on. The first products were car radio power supplies. What has not changed since is the job: take the supply a building gives you, clean it up, hold it steady, and hand it to the equipment in a form that equipment can live with.
What we build
The catalog runs across 13 families and 382 units. Battery backups carry a load through a cut in the supply. Surge protectors take the spike that arrives ahead of the storm. Rack PDUs split one feed into many. Then there is everything that carries the signal rather than the power: copper and fiber, patch panels, KVM switches, video cabling, USB docks, and the racks and mounts that hold the rest of it off the floor.
Model numbers are the through line. 297 of these units carry one, and the prefix tells you what family a part belongs to before you read anything else. There is a searchable list of every one of them in the model number index.
How this site works
This is a catalog, not a checkout. Every unit here links out to our retail partner, who holds the stock, takes the payment and gets the box to your door. We write the pages, sort the sections, keep the specifications straight and build the tools that help you pick. Prices shown are what the partner last listed, and the figure on their page is the one that counts.
Two of those tools do most of the work. The load calculator turns a list of equipment into a watt figure and shows only the battery backups rated to carry it. The guides cover the questions that come up before the hardware does: what runtime actually means, how joules are counted, what a rack unit is, why a cable category matters.
What we will not tell you
We do not claim a unit does something it does not. If a battery backup has no published runtime at your load, the page says so rather than inventing a number. If a specification did not arrive with the product data, the table leaves it out instead of printing a dash and letting you read it as a zero. Anything on this site that looks like a measurement is one.
