24Volt AC to 24Volt DC

Bod · May 18, 2009

What do I need to change a 24Volt AC supply into 24 Volt DC Supply.

It is to power a small LED flashing light for an automatic gate the light wont work on the AC current is there an easy fix for this ? Thanks

Put a rectifier in your circuit that will convert your ac to dc

Make sure you ask for a full wave bridge rectifier, its a much smoother peak to peak.
You can pick one up at laskys no problem.
If you have anything fussy with regards to its dc output then a polarised capacitor in parallel to the output side of the rectifier smoothes things up even further.
Hope this helps.

Your rectified output voltage will be about 34V though (24*1.414), so make sure the fittings are suitably rated!

You can always put a suitable drop resitor from the output to ground to remove the extra voltage

The LED light has a range of 24 -36Volt so that should work fine Many thanks everyone!!

Wow, didn't know Laskys were still around!
