The pictures below show a tower design that has two separate outputs with the ability to adjust a DC voltage from 0-20 volts and also 0-40 volts. The power
supply is intended for laboratory experiments but the design could also be used for other purposes. The current capacity is 10 amps and 3 amps.|
This is a conventional power supply, ie low-frequency transformation from high to low voltage via a conventional transformer, rectifier and capacitor to a stable DC voltage - it is not a switched mode power supply.
Great emphasis has been focus on various protection functions: Line filter, thermal protection for both the transformer and the heat sink - in addition; start and short circuit protection.
For this project you can choose VAD which is a digital volt and amp meters - suitable for power supplies. VAD has its own page and can also be used for other purposes.

In the zip-file can you find everything required to implement it (manuals, diagrams and PCB-files)
- except to realizing it.
