I am in the process of building a height-adjusting desk. I am pretty good with computers (I'm a programmer), but I never learned much in the way of electrical engineering.
I recently purchased two Eco-Worthy brand linear actuators. They each have an 18-inch stroke and a 320 lbs. static load bearing capability. They just have two wires, the positive and the negative wires. They are supposed to operated at 12 volts with a 1 amp minimum and 3 amp maximum.
I intend to operate them both at the same time in the same direction. So what I am unsure of is primarily the power source. My understanding is that I would still use a 12 volt power supply to power both at the same time.
But will I need it to have a 3 amp output or more than that? Will the amperage be reduced as it is divided among devices? Am I misunderstanding how this should work?
Also, if I get a momentary rocker switch will I wire both together and then to the switch? Should I get a relay to run this through? Any recommendations on how I hookup the A/C power to it? Since it won't have any plug inputs.
Here is a link to the info about the actuators I purchased. Any help in figuring out the electrical setup is welcome.
