hai,
I am designing a benchtop power supply with adjustable voltage & current.I want to incorporate overcurrent protection in case of short ckts. Can any one help me in this matter. Can i use any high current relays to isolate the ckt incase of short ckt. My tranformer is of 230/30V,30VA on load.At the moment i used LM317 and may replace it with L200 regulator.
Also I want to use a 7 seg display to dispay the voltage/current adjustments by using a microcontroller like PIC. How can I convert the 1.2-30V DC ouput to 0-5V range to input to ADC of PIC.Is it possible to use any comparator to this job?
Thanks
