Hello,
Page 4 of this AC line filter datasheet rightly states that these line filters should not be connected up with their outputs in parallel with other AC line filters of the same make. (due to imbalance of current flow in the internal common mode chokes and subsequent saturation of these common mode chokes).
However, please confirm that if each line filter is connected to the input of a mains isolated SMPS, ( and not paralleled to another filter) then its perfectly fine to parallel the isolated outputs of these SMPSs. (obviously ensuring that the correct paralleling circuitry is included to ensure current share)

-though you might expect a little worse Common mode problem in say one of the common mode chokes amongst the paralleled bank of smps modules, you surely wouldnt expect there to be a problem of common mode choke saturation. A power supply consultancy (not related to the module company) has said that we must pay them a big fee to do a special paralleled SMPS solution for us, using these synqor modules, because if we do it ourselves, by paralleling the smps module outputs, then we will suffer saturation of the common mode chokes. I believe this is nonsense, do you agree?
