I don't know yet Bob, the spec I gave is from the mfg and I'm sure is worst

case, I imagine in this lightly load application, it will be

  >.5 amp.

Thanks, Tim


	


    Hmmmm . . . okay, except that inrush currents will be

    rather spectacular compared to the load currents.

    When you craft a duty-cycle limited controller, I'd

    recommend that transistors in the 10A class be used

    to drive the motor.
