I'm a electronics newbie, and I'm making a project with 8 24v solenoids playing percussion quickly. I want to power these all with the same power source, so I'm being careful.
This is similar to power supply unit for Arduino/solenoid project but different in the fact that I am trying to sense-check what the manufacturers say about their products.
Some solenoids are spec'ed as having a draw of around 350mA: http://www.adafruit.com/product/413
And others are spec'ed as having a draw of 2A: http://www.amazon.com/0-7kg-Holding-Force-Solenoid-Electromagnet/dp/B009PMCSFO/ref=sr_1_4?s=industrial&ie=UTF8&qid=1431813437&sr=1-4&keywords=24v+2a+solenoid
Are these two options just different in terms of the power of the solenoid's movement (i.e. the 350mA will be considerably weaker than the 2A)? If I went for 8 x 2A 24V solenoids would a 20A 24V power source be enough to power everything at its peak usage?
