I am looking at the wiring instructions and I don’t see mention of any filter capacitor on the output. Every other PS I have seen has one

Why the missing capacitor? Omission? Not needed?

Should I add one? If so what size

Thanks

Hi saildude.

Filter capacitors are built into the board but if you need additional filtering, you could add a 100uF capacitor across the output if you wanted too.

Thanks Chris

Just ordered a couple and one other question - how do I attach the heat sink to things? I thought I saw some tape at one point but was not able to find it again - or would a small amount of super glue or epoxy also work?

Thanks

Hi saildude.

There are special thermally conductive adhesives that would be best for this, but a drop of regular super glue or a tiny amount of epoxy would work OK as well. You want only just enough to get the heatsink to stick. (less is better here.)

Thanks - have both superglue somewhere and regular epoxy - an I will remember to have a thin glue line
