I live in an area that often loses power during storms. I have a Dewalt gas power generator that I use as a backup. I have an expensive computer system and need to run it off the generator. I spoke with Dewalt technical support and they do not recommend running computes off a generator. So I need to "clean" the power line. After several days research, this was the best choice. It is a dual converter that does not bye-pass the system at any time. AC to DC, then DC back to A.C. Output, clean power. It comes with monitoring software that is very good. It can monitor the input and output frequency and voltage. The documentation recommends not using it off a generator (?), but I did not find this a problem. The software on the disk did not support Windows 7, not a problem went to their web site and down loaded the latest version that supports Windows 7. Also spoke to technical support on setting up the software. I give them the best rating for technical support. He gave me a ticket number for future support that would refer me back him if needed.
Used it for a week now, here are the results. Power company input 123.5 V, 59.8 Hz, Output 119.9 & 60 Hz. Gas Generator input 113 V & 62.1 Hz, Tripp Lite SU1500XL output 119.9 V and 61.1 Hz. The results fluctuated, but this was the worst case. Yes the dual fans are noticeable, but can live with it knowing my computer system is protected. Technical support help me set up the software that will shut down my computer if there is a total loss of power, then it will shut itself off, then when it sensors power again it will turn on and reboot the computer. (have not tested this scenario yet). Recommend this system.

This UPS works great with no problems on my generator. Definitely worth the money. I tried cheaper UPS units and they won't operate on AC power (they switch to battery) when the generator is lightly loaded and the frequency approaches 63 HZ. Thanks Tripp Lite for designing this great UPS, and I also really appreciate the professional software. And, thanks again to Amazon for the best price and fast shipping!

This is at the moment one of the most affordable, double conversion UPS available at this writing.

This product is of high quality build, and of course its performance is good as well. Output power is very clean and consistent.

Of course as with other double conversion UPS, the cooling fans on this device is rather loud, and they run at all times, even if the load is powered off, and even if the UPS is powered off. They can only be shutoff if the UPS is powered off and unplugged.

For those who plan to mod the fans there are a couple things to know first. They are standard 80mm fans. They have a proprietary pin connector and wire arrangement. The new fan RPM can't be too low or the system will detect a fault.

This is a great product and a true Online/Online design.

For more sensitive equipment it is a good deal and a no brainer.
