Hi Alan,
Thanks for your feedback on the PSU. There certainly has been a lot of design time put in to it. The build itself only took a fraction of the time spent on design / component selection.
Yes, the main 18V units are Meanwell ones that have an integrated fan. Without it, they are limited in output current to 17 Amps, which may be enough to run a bucket or two only.
The two supplies have not been linked via their protection, but I had in mind to install a relay latch so that if any one 18V rail goes down, the other gets switch off immediately. I believe CML Audio already make something like this that can be retrofitted at the console end.
All of the above is the reason I have no intention here of going head-to-head with the likes of Atomic. They have a reputation at stake and have built that, liability and potential consequential losses into their design and price point.
Anthony.
