what do you mean by capacitor doesn't work at 24V?
I thought that maybe it's value is to low so the charge is not sufficient to provide enough current to trigger TRIAC.
Do you perhaps have some suggestion?
Hi guys,
I am having problem with triac conducting.
In attached schematics triac should control current through R1 by turning potentiometer. I found somewhere on the net schematics and i thought it will work, I dont have to much experience with TRIACs so i would like to hear youw suggestions...
7915 is connected corretly, i know for the different pinout. And diode is correctly connected, polarity is same as in picture :(
I tested this configuration on breadboard and it worked :/ maybe it is worng layout on PBC, i will double check it ;)
hello!
I have problem with output on this circuit :/
I'm getting -20 volts on negative side while positive side give me 15 volts, so i could use some help to solve it :)
hi!
I need 18 volts supply, since i'm having 12 volts transformer i decided to use full wave voltage doubler to raise voltage to 24 volts.
But at the output of doubler i'm getting 36 volts :/ and after pluging it to LM7818 at the output of regulator i'm getting 3.5 volts :(
In datasheet of...
