Hello,

I am interested in these questions, please help me.

1. Power Factor Correction Chokes (Designator: L6) missing from the main BOM, present on the diagram

2.  Input filter MG10000842  (Designator: L1, L4). The specified value of the inductance in the document MG10000842 is different from the circuit.

3. Resonant Choke LR100002800 (Designator: Lr) Wrong inductance value in document LR100002800.

  1. Resonant cap Cr value is 480nF (you have to see all the resonant capacitances in parallel in this configuration)
  2. MG10000842 value is 6.34mH in the schematic its wrong reported)
  3. L6 in the board is replaced by a short, was previous insert but removed cause no needed for pass EMI and surge test
  4. TF20000730 is TR1 in the schematic
  5. LR value is 6µH (see the correct attachment)

hi there, 

can you send us the screenshot where you find the difference. 

Thanks.
