[MRCA] High Current Power Supply Problems

[B. Smith]

I  have never recommend the use of  batteries floating on a 28 volt line for 
safety reasons.
For my high current ops I use two power supplies in series to supply 
dynamotors.
However the  power supplies are diode isolated to prevent them from "talking 
to each other" and tripping different sensors.     :-)
This also prevents possible damage to pass transistors, over voltage 
circuits, over current sensors  etc. as  was mentioned by WA5CAB in his 
post.
