Another excellent capability is that the output voltage will change only by 0 01 if the input voltage fluctuates.
0 50v power supply circuit.
The entire design is transistor bjt based and is virtually indestructible.
What is a variable power supply.
I think i may have misread the scheme in the electrical or electronic circuit books.
Laboratory power supply is characterized by its wide adjustable voltage range and its robustness.
Audio 144 basic function circuits 135 bio.
0 30v variable power supply at 3a two resistors r1 and r2 limit the overload current.
Simply said it is a power supply that can adjust the output voltage or current.
This power supply circuit is highly stabilized that its output voltage will drop only 0 005 even though the load changes from 0 to 100.
The maximum current can be increased if we add the power transistors needed.
