Tripp Lite's OMNI500ISO offers complete UPS protection with built-in line-interactive voltage regulation, intelligent monitoring and unattended shutdown capability. Built-in isolation transformer with faraday shield offers full isolation and complete common mode noise rejection. 500VA power handling capacity supports point-of-sale applications, computers, internetworking equipment and home theater systems during commercial power failures. Line-interactive voltage regulation corrects brownouts as low as 83V back to normal 120V levels, saving battery reserves for use only during complete power failures. Built-in USB communications port works with PowerAlert Software and cabling to provide automatic unattended shutdown of connected network and PC applications.

1 out of 5 eggsWorthless

Pros: None

Cons: Purchased two of these within a timeline of 3 months. BOTH have blown out – as-in the battery still works but the rear outlets no longer produce any power.

The first purchase lasted less than 3 months. The second purchase lasted less than 24 hours. The load on these was under but near the 300 Watt limit.


Other Thoughts: Don't waste your money. I will not be purchasing from Tripp Lite again. Spend a little extra and buy another brand.

Manufacturer Response:

It is difficult to diagnose what happened without more detail. Please contact Tripp Lite’s Chicago-based Tech Support team at 773-869-1234 so we may troubleshoot the issue you are having with the OMNI500ISO. Additionally, this UPS is covered under a 2 year warranty and we will be happy to replace the unit if necessary.

5 out of 5 eggsVery good prduct

Pros: We purchased this for a computer that's used in a harsh environment with very dirty power. Multiple PCs and several UPS devices have failed at the location, but this has been running strong for quite some time. I would recommend this to ANYONE that has dirty power and wants the benefit of a UPS for mission-critical hardware

Cons: The price, since it has an Isolation transformer it's more expensive than your regular model. It also bumps the shipping up some due to the added weight.

Other Thoughts: I'm purchasing another one for a PC that's on dirty power and starting to act up. This is VERY CHEAP insurance!
