Hello. I have a question:
Is it possible to get split power supply by connecting two single switching power supplies as shown in the picture? And what will happen if they have slightly different voltages (+- 0.1-0.2V)? Power is required for the tda2050 amps and active filters based on the op-amps.
I am aware that it is better to use a transformer for such a project, but for a number of reasons this is not possible.

make sure they are identical units and follow the correct polarity to get that split supply, i do that all the time..
Most important, they must have floating outputs, not ground referenced, so they can be connected in series.
All Mean well power supplies can be connected in series. The DC voltages need not be equal.

There might be some spurious effects when two supplies share the same ground line from the load chassis. The ground line might become a sense resistor for both supplies. A star ground would be needed, IMO.
Make sure if one PSU folds back, does not damage your system.
Operate the PSU with less than 80% load to avoid this.
