I have been wondering if a din rail/smps is a good option for an audio power supply. One that I have been looking at for 24 VDC output is the SDR series by Meanwell. The noise is a repectable 100mv @20MHz and with a filter should be able to be reduced. Is there any negatives with using a din rail system for audio? This is the link I was looking at https://www.bravoelectro.com/sdr-120-24.html
Thanks for comments.

I have a SNR 240-48.
The SDR line should be fine because it has a 150% overload capability which meets the demands of music reproduction. The output should be very clean from the data sheet.
The Din rail often is used inside modular build appliences, making exchange simpler.
If you plan to drive it hard and use it flat on a side, consider a low speed, low noise fan to keep the air circulating. It seems to be made for being mounted facing upwards. You even can adjust the voltage a little, if needed. It does not make any noise when running.

Thanks T2,
I was thinking of using 2 of them in my ACA basic unit. I am not sure about the mounting, ie: flat horizontal rail about 20mm off the base or to put the rail vertical on either the inside of the back or front panel with a 20mm spacer for ventilation purpose. The rail and smps would be suspended, so air flow from bottom and through the top of enclosure, like a chimney effect.
Anyways, thanks for the info, very helpful.
