I have a question on PWM. If I have a 48 volt DC source and convert it to a 50% PWM signal can I use this to drive a speed controller that is only rated for 24 volts? i.e I am looking for the best way

    NO!!!! It will put out a 48v pulse and supply 1/2 the current. It works fine for controling motors, becuse you can very the pulse to what speed you need.
    What you need to do is use a voltage regulator to bring down the voltage or get a diferent DC source.
