hi
i have a sysytem works with linear power supply,but i have a problem to switch from 110 to 220v .
i need a shematic that can know electronically 110 v or 220 v,like the LED will turn on if the voltege is 220v .
pleas if anyone has this shematic for that circuit send it to me

220v detector schematic

I think it's really easy to do...

Take a look of the following circuit. Hope it can help.

220v detect

thank you very much for your reply.
this is the circuit iam looking for thanks again
i need the real vulue of the componant that you use in that circuit

110v/220v switch diagram

Hi,

But we are speaking of detecting 110v or abouve. Or one bit logic to tell in the line existes 110v, and another bit logic to tell the presence of 230v?

Re: 110v/220v detector

thank you for your reply
but the schematic we have doesnt show any values of the componanant used on it.what bits do you mean,i do need the circuit can detect 110v AND 220v .pleas if you have any other circuit send it to me
thank you very much guys for your help

any adea guys
pleas if you have any adea about he assue above send it to me
thanks
 

Re: 110v/220v detector

Hi
I have one idea is use peak detect (the circuit can be use by
diode + Cap) ,
 

Re: 110v/220v detector

how you make a peak detector
do you have any accurate schematic??
pleas send it to me
regards
 

Re: 110v/220v detector

You want an optoisolated one? or not optoisolated?

Re: 110v/220v detector

hi
optoisolated or not doesnt matter
you can send me both if you have them pleas.
regards
 

Re: 110v/220v detector

I will draw in the weekend a schematic for you!
best,

Re: 110v/220v detector

thank you very much sonic
that is the shematic i was looking for
thanks again
