Hi,
I have some spare parts arround:
-> a 100W AC220V-AC12V coil transformer, output frequency 50Hz in Europe
-> several 60W AC220V-AC12V halogen transformers, output frequency ~50khz
I am building some light sources for photography with LED strips and chips.
Though not sure for the coil transformer a diode bridge would make it to "raw" DC.
What about 50khz. Would the bridge work well.
Even for further 12V led supplies. Old halogen transformers are so cheap now, wonder if I should buy some more for further 12V transformers.
A 12V/60W transformer is >15$. Such a halogen transformer is less than 3$ on ebay, a shotky diode less than 10c. (BTW SS12 would be good for this I assume). Or the poor LED's need some more care in terms of current etc?
