Paralleling Power Supply Units Made Easy ???
I am considering paralleling a couple of 20a variable adjustable psu's for 40a charging. According to what I have read on the world wide inter-web, it can be done quite easily, provided the following ...

With 10-turn pots adjusted at the maximum I potential (to equalize) the difference in generated amperage is so small as to be insignificant. As the amperage drifts downward inequality becomes more apparent and in essence a moot point. Who cares if one 30 amp unit is developing 22 amperes of current and the 2nd PSU is at say 12 amps? The load is being satisfied. The keys are resolution in identical pots and environmental equality of the two PSU units. When three or more units are paralleled then inequality becomes harder to resolve.
