Is a UPS suitable?

Question

Uninterruptable power source

There is such a thing: agregator-stankov.ru/stanki-plazmennoj-rezki-s-chp...
Such an uninterruptible device was selected for it: https://barnaul.e2e4online.ru/catalog2/Periferijno... An
uninterruptible device is needed in case power outages, so that in which case it’s normal to turn everything off, very long work is not needed there.
In terms of output power, an uninterruptible power supply is suitable (there a computer goes to the machine, a separate uninterruptible power supply is taken for it, the computer is not taken into account).
The problem is that looking at the dimensions of the machine and its purpose, to put it mildly, they doubt that not only this UPS, but in general any other one will work fine with it, and everything will not be cut down when the machine is turned on.
I, as an enikey worker who is practically not versed in power supply issues, have a question - what other parameters should I pay attention to in order to be completely sure that the UPS is suitable for work?

Answer 1

Will not fit offhand. The power reserve should be at least three times. There, the power of the machine is reactive - electric motors, inductances.
