General Purpose Power Supply
You can select the output voltage range by 0-30V or 0-40V of 0-60V. The component's value will be different depends the output range you choose.Vout ------ Iout ------ R1 ------ R4,R5 ------ R9 ------ Tr1 ------ C1/C5 ------ IC1 ------ Tr2 ---------- Tr3
0-30V --- 1.3A------ 0.47Ohm---33k ----- 2k7 ----- 24V/2A --40V-----723 -----BD242 -----2N3035
0-40V --- 0.8A------ 0.82Ohm---47k ----- 5k6 ----- 33V/1.5A --63V -----L146-----BD242A-----2N3035
0-60V --- 0.6A------ 1.2Ohm ---68k ----- 19k -----48V/1A --80V -----L146-----BD242B -----2N3442
Please check the output current since higher voltage output will decrease the current output.
