I got it to replace the previous model that I had for 20 years... (the previous one got burned).
The important thing about this is that it has the smart cart, where you can insert a network card and get information about the power at more than one point, for example, computers + NAS together. However, to avoid confusion, you need to buy this card separately. It has the same network connection, but only for 2 basic things, which are almost useless to me - that is, to check its status. The important thing is to update the network with SNMP and be able to access all its parameters, which can only be done with an additional network card... which are now available in many used ones, relatively cheap...
So, the smart connect is useless to me because it doesn't send the information anywhere for you to use.
The USB connector has confused me; it's not the usual "male" USB, but a regular USB, so I had to buy an additional long cable from abroad...
In any case, you shouldn't place it near you because it emits a high level of EMF radiation, which causes cramps and pain... keep it away from your feet, your head, far away... and connect it either through the network or a long USB cable to your computer...
The menu is a bit confusing, but again, if you have the network card that you buy separately, all of this is simple. In the previous one, I had to use a serial terminal to make changes... This one, on the other hand, has an Ethernet connector for a serial terminal, but it doesn't come with an Ethernet to serial cable. Strangely, it didn't even come with a power cable - only 2 cables to connect its output to a device. And the power connectors are not female plugs, but computer power connectors. You need cables and adapters that support them...
It doesn't make noise, except when the fan needs to turn on.
Why spend so much money on a UPS when there are much cheaper options? Because it has many controls on the input and output, and nothing will get damaged when something bad happens... that is, if something gets burned in it, your machines won't get damaged due to poor power.
I haven't changed the batteries in this one yet; in the previous one, I found equivalent ones at a much better price than the ones sold by this brand.
Also, if the power exceeds a certain limit, it automatically corrects it, which is also important for protecting your devices.
Also, I don't hear any noise from the coils, while in the previous one, there was a loud noise coming from the transformer.
Currently, I'm drawing 300W, and it's at 25% of its capacity..
