Hey Guys,
I'm using a mr16 to control my yard train for this year's show.
Any ideas on what I could use as a high current dc motor controller, that would be driven by one of the mr16 channels?
The motor I'm using is a power chair 24vdc brush motor, and has a stall current around 30 amps or so.
I was thinking of using something like the Crydom D1D60:

During testing of the mr16, I've been driving a small 12vdc relay from one of the channels, which I had planned on using this relay to then control a much larger solenoid that then would switch the motor on/off- but the problem is that running the motor at 24 volts, I think it will run too fast. Not certain that I can run it at 12 volts (1./2 votlage) without overheating issues. Therefore I need some method to reduce the motor speed.
I've also considered using a typical electric scooter cotnroller, but these have hall effect throttle controls, and I haven't figured out an easy method to interface the MR16 to the throttle control inputs.
Any other ideas?
