4. Evaluation data
DC300V DC600V DC900V
This data is using DCIN
Tested one hour after switch on. ( Thermister hot situation )
Using ACIN input low voltage situation, Efficiency little bit low down.

DC from ACIN
AC from ACIN
This board has two input terminal. DCIN and ACIN.
Efficiency depend on input terminal.
Because of input impedance not same.
