Generally, we find this out when someone posts to the list asking for help with a new UPS.

Here are some general thoughts on why this is a difficult question to answer:

This is a little easier to answer. For the Eaton and Powerware brands, we can often ask the company to help out with technical information. Several other companies have provided tech support or protocol information. Some of this is visible if you choose either "****" or "*****" from the "Support Level" dropdown on this page:

On the other hand, I personally can't recommend new APC equipment now that they have started using a proprietary protocol that several customers have been unable to obtain documentation for. I have an old APC USB HID UPS, and it works well, but their new equipment is apparently more limited in what it can monitor.

Short answer: buy from a distributor that allows open-box returns. The NUT project can't be liable for recommendations based on old information.

If you can provide a little more information about the kind of UPS that you are looking for, I'm sure we could narrow things down a little. Are you protecting desktops or small servers? A whole machine room?
