Since Modular Grid lists that spec, users think they can just add all the figures up and get a supply that claims it can handle it and be ok. So, they buy $3500 worth of modules and at the last minute throw a $75 uZeus in there and expect it to work. It has been mentioned that inrush current should be calculated, the consumption is dynamic and that there should be some way to warn against the tendency for switching supplies to not start if they are loaded heavily. You know, the kind of stuff of which most users have absolutely no understanding. ;)</div><div class=""><br class=""></div><div class="">Mark</div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><div><br class=""><blockquote type="cite" class=""><div class="">On Oct 22, 2017, at 10:07 PM, Quincas Moreira <<a href="mailto:quincas@gmail.com" class="">quincas@gmail.com</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div dir="ltr" class="">That's good to know Mark.

The problem is, each new designer that enters the forum proposes that everything be changed to his way.<br class="">

I think Rails should be magnetic and power connectors like magsafe right on the rails. 15v DC and each module would subregulate for 12v Bipo. 1.5mm stainless panels (due to the magnetic rails)<br class="">
