How to make a variable feed. 1- Adjustable voltage current supply 60V and 0-10A

Hello friends, I have shown you the construction of a current and voltage regulated power supply that can handle 5 amps using the BD139 and 2SD1047 transistors with the LM317 integrated circuit. LM317HVT (60V) and BD139 1 piece is enough. You can easily use this circuit in constant current and constant voltage applications. If you are going to use the high current circuit for a long time, remember to cool it. thank you for watching

This diagram shows how to make a precise regulated power supply from 12 Volts to 20 Amps. In fact this diagram is a working basis for power supplies from 5 Amps to 150 Amps. For a 5 Amp power supply, a single power transistor added externally, the 2N3055. With 4 2N3055 in parallel we obtain a current of 20 Amp. We calculate 5 more amps per added transistor. Based on the LM723CN integrated circuit which offers us, in addition to being variable from 2 V to 37 V, very good regulation precision in the order of 1.5 millivolts on 5 load amps.
