Variable 5VAC galvo driver circuit?
I have a "Skyman" galvo "system" (basically a GM-20 type galvo with a mount and 1/4" audio jack) that recommends using a 5VAC, 1 amp power supply along with a potentiometer for driving the galvo and mirror positioning across its full range. I would like to be able to use a variable 1-5VDC or 1-10VDC voltage (from a DMX decoder board I already have) along with a driver circuit to accomplish the same task, in lieu of using the manually-adjusted potentiometer.
Any recommendations on a specific circuit and components that might work for this application?
Thanks!
