This is the schematic of the 30V/2A power supply I use in my own lab.It may look very complex, but it really isn’t very difficult to understand: it uses only the knowledge we’ve learned in the previous lessons.
The top part looks like the power supply we built in Lesson 7: the transformer L1 transforms the [...]

It is a simple circuit regulated power supply, based on the known UA723, that drive a transistor Q1 [2N3055]. The regulation of voltage, of expense becomes with potentiometer R1 from 0v-30v DC roughly. In order to we achieve 30 V, will should the transformer of supply TR1, it gives all the current that it asks [...]

If you want used easy variable regulator power supply voltage 0-30V at current 1.5A max. I am like this circuit, because it is small but very good. View Circuit
I uesd IC - LM317T it is quality products ic variable regulator,so i like make in other power circuit.
I made use of a 24Vac 1A transformer,The [...]
