UPS for 120W CO2 laser engraver (lemm.ee)

I've been trying to figure out the peak power demands and an uninterruptible power supply that can handle it. There doesn’t seem to be any documentation for this. It just needs to run long enough to power off safely. It's a Trotec speedy 360. Any help would be greatly appreciated!

Edit 360 not 400 and it's an 80W laser

Solved!

I would go off it the max wattage of the power supply the whole system uses instead of what the laser says.

That will have you covered for peak draw over the entire duration you're looking for, and will likely end up giving you a lot of wiggle room time wise.

I know almost nothing about laser engravers, but many of them are mechanically similar to 3D printers, which I do know a lot about, and stepper motors can suck down a lot of power.
