I am wiring this up, and I would like to limit the current being drawn from 18v DC/DC converter.

What would be the simplest way of doing this?

    Yes, that is wired correctly.

    Did you get the 5 amp current sensor or the 30? The higher current ones output less voltage per amp, which will make it harder to measure small currents.

      I got the 30 amp. My thought was that the motor uses up to around 20 watts when running so a little more than 1 amp, and as far as I can tell, it tries to pull around 6-10 amps(!) when stalled/almost stalled. I think this should mean a fairly large spike, that I should be able to detect even with the 30A device.

      But of course it is probably just absurd overkill, and will make my life more complicated. Fortunately they are absurdly cheap and easy to buy, so if the resolution turns out to be a problem, I can get another range, when I have some empirical data. The other ranges should plug in, in the same place right?
