AC diode

Postby biggusdickus » Mon Nov 16, 2015 6:58 am

Hi New to Electronics.

Is there an AC equivalent to a DC Diode.

I am using 24vac with power from 2 different sources at different times and 18 separate outputs.

Cannot change power to DC via a bridge so power must remain 24 vac.

I have a LED at each power source point to tell which power circuit is on.

Trouble is no matter which circuit is on , both LED's light up.

If I was using DC i could overcome this with a diode at each LED to prevent feedback.

Is there a diode equivalent for AC current?

Current is a max of 100mA.

Appreciate any help offered but please keep the terms simple for a newcomer.

Thanks

I don't think there is an AC equivalent.
Are you saying that you have two 24VAC sources that supply 18 devices, and if one AC supply goes down the other supplies them? But, both 24VAC sources can be on at the same time?

a diode is a diode dude, theres no such thing as an ac diode, generally, if your ac frequency is 60 hz or above its pretty hard to see if its going off and on, cause its cycling 60 times a second, so if you see a tiny shimmering in your leds or even not its probably working fine.
