Thanks Ray, that voltage regulator looks like a good solution. I was also looking at this one

I’m in Australia, so some amazon options are not available.

I’ll be sure to use the barrel jack.

I assume 2A will be enough? Most of these regulators seem to be limited to 2-3A max.

My latching solenoids need a min of 9v so I’ll need to keep the voltage above that, or does the controller generate a higher voltage when switching them on/off?
