Power Supply, Current and Voltage Regulated. Also Adjustable down to Zero Volts!.
Güç Kaynağı, Akım ve Voltaj ayarlı, Ayrıca Sıfır Volta Kadar Ayarlanabilir!
Note: Both Current and Voltage Regulation is Extremely Important to Help Prevent
Damage to Circuit, Especially Experimental Circuits.
In this circuit I have used a Rotary Switch to select Various Current ranges
as a Potentiometer is not very practical for the lower resistance/High Current Ranges.
But if you wish to change it to a pot, you can try it.
** It is practical to use a pot on the lower current ranges so the lowest switch
range could be a pot with a small series resistor. Allowing for adjustment from
say "10 mA to 500 mA". Than use fixed resistors on the higher current ranges.
This circuit will give you a Very Simple, but a quite versatile Voltage and current
regulated Supply. And Down to "Zero Volts" out is a Nice Feature.
