Whipping a cheap LED PSU into usable shape | EDN


This interesting article analyses some cheap mains AC to 12V DC power supplies and how thet can be fixed to work OK. With some modifications they can be used to provide power to LED lighting.

The writer of this article has a continuing love-hate relationship with Cheap Chinese Chotchkes – in this case, 18W power supplies small enough to fit into an electrical box.

I say “18W” (well, the website says 18W), but those are Chinese specs, not to be confused with actual specs.
