I get a problem of this 0-30 Vdc Stabilized Power Supply

[cyw1984]

0-30 vdc stabilized power supply

I have couple of questions of this project.

How could it change the P1 and P2 to be Vref for D/A convertor 0-10V
and how to caculate the resistor????

Thanks a lot

You want to set the output voltage and current limit with DAC's?

For the volts remove P1 and feed a voltage into point 12 with the DAC ground to point 4.

The current limit is a bit more tricky.

sorry for my english
what mean of The current limit is a bit more tricky
how to replace DAC Verf I ????

Added after 23 minutes:

What type of this supply??
linear - LDO..NPN or Quais-LDO??
or Switching Rugulator??

hi
it is better to use LM723 regultors.
and it is easy to matche it whit adc.

HELP!!! I NEED A POWER SUPPLY WITH A regulated 12V and 9V OUTPUT.HOW CAN I DO THAT?


THANK YOU

Hi,
first of all i would like to say, "breneer ", it's not good idea to put your question in other people question area. but still, The Power supply u asked for is very simple for which i'm sending the diagram. Use the voltage regulators with Heat sinks. The MAX current is 1A.

Bye,

Take care next time.
