Can I run two UCD 180 modules off of one Meanwell S-350-48 SMPS?
As numbers imply, it is 350VA and 48 DC volts, a good input voltage for the UCD 180.
Second question would be, what do I run into the the ground input of the UCD 180? Do I connect the Meanwell ground to the input ground of the UCD 180, or do I ground the UCD 180 to a chassis ground?

I also have a robust 650VA transformer that is made for hypex modules and a Hypex power supply module, but I do not have a soft start. it will not be here for two weeks.
I wanted to see how the SMPS would sound. I could go with the linear supply, but without a softstart do i risk blowing the amp modules?

most UcD build run GND direkt from amp module to PSU.
you will not blow your amp without softstart. but maybe you will blow your main fuse on startup.

On the specification it is called Single Output .... so I do not think it is a +- SMPS .... the ground is for the input, Ground and not common ..... ...

sounds great. so you have 1 650VA trafo.
one 40.0000uF PSU?
or 2pc 20.000uF PSU's?
1 softstart, from hypex?
2 pc UcD180. ST? HG? HG with HxR?
not a hypex softstart, but should be fine.
2 UcD180 AD. several years old, been in my closet for 3 years.
1 UCD power supply ST, which according to Hypex can run either 1 or two UCD 180's. So i will use it to run both, see how they sound, but likely upgrade to a larger supply down the line.
