As a rule, the Pittman won't draw any more current then other motors that would be suitable for powering that MTH steamer, so I don't know how you arrive at that conclusion.

John, the issue was that the 4400 couldn't support the 'stall current' of the motor. I think when running off AC and sending the DC by PWM, the 4400 was seeing the peaks of the pulses as close to stall and would shut down the card using it's own protective circuitry.

Maybe it's different when going directly off DC?

Anyway, you were the first to warn me that the Tsunami 4amp wasn't going to work with my Pittman. But that was a couple years ago.

Here's a link to the thread: https://ogrforum.ogaugerr.com/...7#155293810601170117
