I was looking for a small 12V AC-DC unit and I found this interesting Meanwell unit on Mouser which is very slim with dimensions of 119*38*18mm.

However it appears to be a part of some larger configurable power supply unit and I haven't been able to find out if it is usable as a standalone power supply or if it would need additional filtering from something like the ONE2 Distro 400.

With a high power density, great form factor, and relatively low price if this could be used I think it would be great for SFF systems.

Does anyone know if this will work?

Looks like this is an output module for a 1U power supply so it needs to be combined with a larger unit. Also looking at the spec sheet the ripple from the 12v unit is 150 mV which is higher than is recommended for computer components.
