0-30 volt regulated power supply main parts of the TL081 opamp and transistors (BD243, BD139, BC548) In addition to the display indicator volt meter circuit ICL7107 made with voltmeter power solid apart from the used power supply and voltmeter circuits Eagle prepared with PCBs schema files there. Laboratory-type power supply will do the trick in many projects.
0-2A 0-30V Power Supply Circuit
from the new laboratory power supply for the smaller size (8.7cm x 7.3cm) than in the original draft (12.5 cm x 8.7 cm). In addition, ARK applied connectors (for the exits, for the measurement of voltage and current measurement for them – this is optional). Pin a regulation voltage and current are placed beside each other, rather than scattered across the plate As I used transistor under BD243 and applied transistor BD139.
