DC-LAB10 - is a power supply deck for laboratory use
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

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