I have aquired some speed controllers for fans but they run off a 240v supply. I was wondering whether they could be converted to a 12v supply.
I'm currently using a varistream but am always looking for alternatives should the varistream fail so I have a short term replacement.
Anyone know about electronics?
?
Was advised that its just the coil that would need changing as the 240v one is too big. 12v always has a smaller coil?
I've tried Maplins speed controller but the amp rating is too low and would burn out in no time.
