Great info. UPS already has build in AC to DC converter, rectifier. That is how UPS is able to charge DC batteries. UPS also has a build in DC to AC converter, inverter. Thats is how UPS is feeding AC loads when utility power is lost.

Looking into a hob for a data center tech. This vid helped out a lot.

Thanks for your very useful information about Power Distribution for Data Centres and UPS

wonderful, I am executing a data center and I found this video as easy, authentic and effective.

2:55 to 4:26 needs correction. An Automatic Transfer Switch (ATS) selects between 2 or more power sources (example, utility power and generator). An ATS does not convert AC to DC. Based on your example, the UPS will receive 480V AC, convert it internally to DC to charge the battery, convert back to 480V AC....

This video is really designed for Data Center interviews. However, you make some good points. So I will review your comments and update the video.

every data center has two main power sources the pirmary one is Utility and secondry one is generator, so power comes from the main utility to the transformer then to MCb or main circut braker, then to MSB or main switch board then goes to main Utiltiy circut- then to ATS and from ATS it goes to rectifier this where the power change from AC to dc and then to invertor to change from dc to ac and then it goes to PDU and from there it goes via bus lines to the client computer or server racks ..

Why would the generator not be wired for fail over of the mains primary? That doesn't make sense to me to have the secondary power just be a generator. I could see if secondary was from a utilities provider and you had your generator on that circuit in case your secondary also went down maybe

The PDU in the rack is supply by a A&B Power Panel, each power panel has it’s own UPS back up,and all is backed up by your generator,most buildings have 2 generators

⁠@@jgould30 It does in reality. The mains output and the Generator power ouput connects to the Automatic Transfer Switch (ATS) or sometimes Auto Mains Failover (AMF) system. It’s the ATS that does the switching between Mains and Gen and viceversa. What you will typically have is The ATS is fed by output of: 1. Interconnections of Mains Feeder + RMU + Transformer + LV switchgear 2. Diesel Generator (s)

Can you do a video on specific SLD symbols and diagrams?

Close... But not quite. One line doesn't look like that at all, actually, but its a useful explanation for lay people. I build data centers.

True. It’s kind of close

remote power panel, does anyone know what that is? please it's really important

@kylelee639 5 ай бұрын

RPP are downstream from the ups. They step down from 480 to 208 or less. Feeding customer loads. That’ll be what the customer 20,30 amp 208v circuits are fed from

How about a inverter and rectifier

@engineeringanddonuts3917 4 ай бұрын

I already did a video for a full-bridge rectifier. And, the inverter is simply a DC to AC converter with a pulsing DC signal generator. The full derivation will require an extensive knowledge of integrated circuits. Does this answer your question?
