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 ...

I am not going to fail four power supplies so I can get a foto op for this forum of a slag heap on a bench top. I managed to find a blue ATO 10 amp fuse for the Meanwell. It is just too damned easy to isolate those PS with rectifiers. Then I can play with pots and voltages all I want. I am kicking myself for even trying a stunt like that. Absolutely nothing to gain and everything to lose including a few thousand miles lost to get replacements. The word DUMB comes to mind. I even have some 250volt .47 uf caps lined up to tame what little ripple the units produce before the isolation rectifiers. After the rectifiers a 5Kuf electrolytic cap waits. It would take an Intermediate Range Ballistic Missile to reach the nearest Radio Shack from here.
I've got several (actually 20) 317 circuits to build to allow the use of 12 volt fans with the 36 volt power supplies. Fans are for heat sinks for the 30 watt LED lights.
Then comes the 200-amp MOSFET circuits. Remote controlled relay function. These guys will operate in parallel mode. Already checked and the remotes can be triggered from inside the rig or house to inside the generator/battery shed. Whoopee no more relay coil drain!
