I’m putting together an order for a 12V linear actuator and a Jrk 21v3 motor controller for it.
I need to determine the power supply for the Jrk. I would like to look ahead, though, when there will be two such controllers and actuators, and buy one power supply good for both together.
One actuator, mounted vertically, will support about 10 pounds. The acceleration will contribute only a few ounces to the force required, so say about 10 pounds total. The other actuator, mounted horizontally, will only need to push with a force of about 1 pound.
The actuators are each said to use half an amp at 12V. Of the dozen or so power supplies that you sell, which would work? Would a 12V, 1A wall power adapter work?
Also, does the feedback potentiometer, which is supposed to be hooked up to 5V, require it’s own power supply? This needs to be a steady, constant 5V.
