The presentation below covers some of the important topics that are top of mind for data center owners and operators today.

• UPS multi-mode / ECO-mode (ESS)
• Financial analysis
• VMMS
• Power Supply Unit (PSU) Tested Performance
• Coordination and Timing of switching (Eco-mode vs STS vs PSU hold-up timing

The audio for the presentation (YG_Loucks_Day2_UPS.pptx) attached below can be downloaded from here.

I recently updated the presentation to include new material (2- and 3-level converters, etc.) and created a voiced-over presentation that you can play by clicking on the image below.  The updated presentation that goes with this is also attached below (YG_Loucks_Day2_UPS_c.pdf).

Here's an updated video version of me giving this presentation. 

With this class I only had about 25 minutes so didn't cover all the material. 

Also, you'll notice the audio changing during the presentation.  What happened was that my lavalier mic wasn't plugged in completely to my digital recorder and I would get popping or other noise.  During those times the audio recorded from that mic was unusable. 

So, instead I switched over to the slightly less clear microphone on the computer or as a third backup, the microphone on the video camera recording the presentation.
