ESS power supply

Hello all,

I'm probably overthinking this but I want to make sure I power the ESS correctly.
I have recently come to realize that I have been likely underpowering my ESS for some time. I recently had to replace my ESS due to some really random machine crashes and I saw visible burning/corrosion on one of the components.

The documentation says to use a regulated supply. I'm having a hard time finding a din mountable regulated supply. I don't know a lot about power supplies so maybe I just don't know the correct verbiage to search.

I did find a meanwell supply that has specs for line and load regulation. Does this mean it's regulated? I have attached a crop from the spec sheet.

Thankshttps://uploads.tapatalk-cdn.com/202...9e839cc023.jpg

So that meanwell supply is "regulated"?
