Hello,
I'm just looking for best practices when attempting to wire DC power supplies in parallel. I'm in need of 48V, 50A and I am in possession of QTY:3 48V 20A power supplies.
I was going to connect each power supply to mains, and each power supply would be connected through a different 20A breaker. Could I use a mechanical switch to turn them all on at once?
Also, should I be using diodes on each DC leg of the power supply to prevent any damage when switching them on?
Together they are powering an inductive load.
