Hiya Guy's,
Rather than just go buy a stepdown regulator I reckon the circuit below will fit my needs. Now I'll be using a 24 volt solar powered battery bank rated at 400 amp/hours and what I want to do is have a variable regulated voltage of no-more than 15 volts so I can power the 12 volt nominal lights in my shed. The specs for these cfc fluro's is a max input of 15 volts. The reason I'm going for a 10 amp regulator is when all 8 light are on I'm pulling around 8 amps on average. Now say if I set the output to 12 volts when the batteries are sitting on 24.5 volts when the batteries are topped up the supply won't be over 15 volts. Now as far as the circuit saying 100mA continious I'll put a small 12 volt fan on the back of the heatsink. I'm open for suggestions on this project and any comments will be appreciated.
Cheers Bryan
