Had to replace a four year old model when the battery failed. Bought the same unit, and it was defective. Tripp Lite replaced it immediately. Second unit was also defective, and again Tripp Lite replaced the unit. Third unit working like a charm. Very solid construction and hopefully this one keeps working!
Using the 550VA ups on our IP phones and switches to keep the systems running when the grid power fails, I have installed four of these ups's without any problems yet.
Excellent fit for the On-q Legrand 42" structured wiring enclosure. Using to backup power to an Arris cable modem, Ubiquity router, and two D-Link managed switches.
This product fills a niche, I haven't found any other UPS that would fit in the structured wiring cabinet as well as this one. And is does it's job very well too. The problem I have with it is that when the battery goes bad, it shuts down even if line power is available. This makes no sense as the primary purpose is to keep power up.
I would recommend this to a friend!

Good packaging, sufficient power connection for small network (modem, router, switch) and surge suppression for cable. Battery is documented as NON user replaceable. The product is very expensive for what it does but there are few other options.
Pros: Enough power connection for 3 devices, Size fits well in OnQ box
The Tripp Lite AV550SC fills a niche that most UPSs can't. This product supplies uninterrupted power flow to devices normally found together in home networks, as well as properly managing power-up. Its delayed power-on for the router minimizes logon confusion, and the 12VDC supply to keep such devices going makes a hard-to-find combination. It's also smart enough to communicate with your computer to arrange for smooth shut-downs in long outages. The ability to be wall-mounted helps manage equipment clutter. An excellent choice!
By far the most important component of any residential structured wiring enclosure should be the AV550SC. Compact and designed for perfect fit in most structured wiring enclosures. This beauty allows all components like modems, routers, switches and distribution hubs to get surge protected, filtered, an uninterruptible power. If the power goes out its good to know these systems will still be able to function. Works best in enclosures where the power outlet of the enclosure is to the far right side. Avoid enclosures with the power outlets in the middle at the bottom.
