Motor control
Hi again. How strange, forgive the phrase, not you. I was given a power supply yesterday, some one knew i was after a reasnable size transformer, on the other end of this psu was a water pump. The transformer was 4 amps rated at 12 volts output, so i was after the transformer, the attached circuit was a rectifier and smoothing capacitor, and two fuses, so if you need fixed voltage speed of the pump thats the way to go, or multi speed control can be done other ways with regulators and or resistors. Dave.
