When the current exceeded tr1 and tr2 will work.
0 50v power supply circuit.
Moreover it s equipped with an over load and over current protection features.
I think i may have misread the scheme in the electrical or electronic circuit books.
Another excellent capability is that the output voltage will change only by 0 01 if the input voltage fluctuates.
Laboratory type 0 50v 0 4a adjustable power supply circuit a classic design based on the tl081 opamp.
Adjustable power supply circuit.
With the variable supply feature it is easy to control and deliver voltage and current to the load.
Laboratory type 0 50v 0 4a adjustable power supply circuit the tl081 is a classic design based on the opamp i think i can remember the misconstrued diagram in the electrical or electronic circuit books.
