[Milsurplus] Switching supplies for dynos

[hwhall at compuserve.com]

Yeah, I'm familiar with that step-start approach but someone had located supplies that didn't shut down when the motors started.  The guys I'm talking to are interested in that brand if I can find out what it was.

  Try putting a low ohmage  resistor in      line to limit the current - - after the dyno spins up by pass the      resistor.  ePay has "resistance" wire or you can roll your own      with small diameter wire.

            I        believe I recall that someone had found a brand of switching        supply that could handle the cold starting inrush of large        dynamotor sets but apparently I did not keep a copy of that        thread.  Does anyone have that info still?
