Dear Sir,
I want the constant current source 2SK117 not replaced by a resistor.
The operation of the power supply I understand, only the choice of the zener diode D3 and D4 is not clear to me, why would a designer to make that choice, I would like to understand.
It is for security reasons?.
Greeting,
Pim
