INTERNETOFFICE500 4.7 5 3 3
The unit does what I expected it to do. I purchased my Internetoffice 500 in February of 2010 for my home office. It has worked well up till now keeping my computer going through a number of power interruptions. I live in south Florida. It has recently become difficult to turn on so I anticipate a replacement will be required shortly. Three and a half years is probably all that can be expected. I hope the new model has a way the turn off the annoying beep the unit makes when it is turned off. I work late at night and it wakes the family when I turn the system off. September 25, 2013
Works exactly as described I have several Tripp-Lite products in my home and home office. I use this one for my work lap top, television and office phone line. It works exaclty as promised and is a necessity in Florida where we have frequent lightning storms. September 6, 2013
Peace of mind alone is worth the price. Great product. Such an important item. It not only protects against power outages. but it also handles electrical spikes. My current abode has none, but my last place had this going off at least once/twice a day. It would sound then stop as soon as the spike was over and all was well. I would never be without a UPS ever again. When power does go out and that's inevitable. there is plenty of time to shut down all the items plugged into it. I would definitely recomment this product.

Is my internetoffice500 unit fried?

With the unit plugged in, I power it on. Neither the green or red battery level lights come on. After about 20 seconds, it powers off, and appears dead.

Answers

Answer: 
The Internet office 500 is not pure sine wave, it is PWM sine wave.

However, we have many products in our offering that will support pure sine wave. In order to make sure the right product is being chosen the following is usually asked for:

Specific makes and models or total wattage of products planning to be connected to the system.
Runtime required in the event of a power outage

For additional info, please reach out to our presales applications team at 773-869-1234 or presaleshelp@tripplite.com.
