Hi to all
i have got the following psu it all seems to work ok but i know that you all gonna spot that the LM317 looks wrong, but it aint
anyway when i short out the output to set the current limit the led2 lights and adjusting RV3 i can make the led dimmer or brighter
so i think it is working.
Now i have got one of them led volt\current meter display things from china, the volts side works ok, but when i connect the
current side ( thick black wire to D and thick red wire to C) and then short out the output the led2 does not light, no mater how much
i adjust RV3, i do get a current reading of about 1Amp on the display while the output leads are shorted ( but no adjustment can be made with RV3) and things start to get warm (the heatsink for the 2x TIP35C and the 47r R9)!
Any idias as to what is going on ? and am i doing things right ?
Meny thanks for any help.
