For a summer project, I’m looking to convert my ‘sitting desk’ to an adjustable standing desk. To do this, I’ll be using two of these actuators: http://www.progressiveautomations.com/images/pdf/PA-04.pdf. Under full load, these actuators in parallel will require a maximum of 24A, I believe. They also require 12V. I’ll need to be able to control these actuators simultaneously (for obvious reasons (like preventing tilting)). Looking through the Pololu motor drivers, and doing research, has left me conflicted. I’ve read that a simple VNH3SP30 can control up to three motors, which would be great because it’s cheap, but looking at the data sheet, this is unclear. I’m no electrical engineer, though, I’m a mechE, so I could be totally wrong . I was leaning towards either the Dual VNH2SP30 Motor Driver Carrier MD03A or the Pololu Dual VNH5019 Motor Driver Shield for Arduino. These do seem a little pricey, but if they’re what I require, then there’s nothing I can do, I suppose. Would one of these two drivers do what I require? Or is there a better way I can accomplish controlling the two actuators?
I’d appreciate any help. Thanks!
