I'm using a 30V DC power supply which is said to be 30V/3A with a switch between series/indep/parallel mode. Connecting the supplies in parallel, we have a maximum of 6A. However, in order to execute my current project, I´ll need over 10A. When we parallel connect the outputs, even if there is a small voltage difference, the internal control ends up managing to balance this difference so the output is the same in both channels.
My DC Supply is meant to be a linear ICEL PS-5001.0014 30V/3A.
Looking at the datasheet of an Agilent DC power supply, I read that I can actually connect two independent linear supplies in parallel. So, I could buy two distinct DC supplies and connect their channels such as I have them in parallel. I was wondering if I could also do it with my DC power supply.
I have this question because, even though I've purchased the supply as a genuine ICEL DC Power supply, I found many other ones from china (this means mine is just a copied version sold as genuine) which may be manufactured with low quality components. My question is, can I purchase another similar linear DC Power Supply, connect its channels in parallel and finally connect the two DC supplies in parallel again (in order to have 30V/12A)? Can I trust in the internal control so it will manage to balance all voltage differences (let's say one channel has V=29.99[V] and other has V=30.01[V])?
I'm attatching a picture of my DC power supply and two others I've found on internet that actually are the same as mine.
