Hello all,
I am new to the forum and need a little help. I need to illuminate some leds. The problem is the only power i have available is 3 phase 240 volt with NO neutral. I have tested a polyphase bridge rectifier to convert from a/c to d/c and then doing a big resistor to limit the current to the leds. This method creates a lot of heat. Can I do the same thing and then use a zener diode to drop the voltage down to 12 to 24vdc. I don't know if the zener will work. The other problem is, I am extremely limited on space and heat is an issue. Does anyone know of a compact transformer/rectifer package for an application like this?
Any suggestions would be greatly appreciated.
Thanks,
John
