The peak and the rms values of inrush current of an SMPS are very different with or without this additional inductor.

A SMPS power supply could therefore burn its input fuse without an isolation transformer, but not with it.

The operation is therefore very different, especially with regard to the inrush current and the waveform of the current consumed.

It is therefore not an advantage in terms of measurements and tests.

If you want to limit the current, use an external device like a 100W incandescent bulb in series with the DUT
