Hi All!

**TL;DR**

Does the form 2 handle cheap UPS’s well or should I get a better quality one?

**More info**

We have had a power outage for the 3rd time during a print now and this time was right when we really didn’t need anything to delay our prints!

We have finally decided to get ourselves a UPS for the work horse (the 3D printer) but I’m not sure what one to get. Basically, there’s two types of UPS’s on the market; Pure sine wave, and simulated sine wave. You may know them under different names so here’s a super quick breakdown.

Pure Sine Wave UPS: generates a pure sine wave (exactly like mains power)

Simulated Sine Wave UPS: generates a square wave that mimics a sine wave.

A simulated sine wave UPS are much cheaper than a pure sine wave UPS. They’re considered to be the “consumer grade” type product, the pure sine wave UPS being the “business grade” type product.

My question is, does anyone have a simulated sine wave UPS and how does the printer handle it? I’m not sure how sensitive the printer is to an unstable power source, and being a simulated wave its much less efficient than your typical mains power.

Any input is greatly appreciated!
