QUESTIONS re: MEGA-WATT 33-AMP POWER SUPPLY
This critter can be found on eBay. It is a switching type power supply. Supposed to have an ultimate amperage potential of 33, voltage adjustment of 10, to 15, and work fine as a long term battery ...

Not an answer, just a question.
The statement that they will burn out if parallel makes me wonder why. Is it that if one supply is set for a higher output voltage than the other it will supply a high current back into the lower voltage supply? (The lower voltage supply can sink current as well as supply it). If not then it seems that the higher voltage supply would just supply all the current and be limited as if only one supply is not connected. The lower voltage supply would do nothing.
If it is because the supply can sink current as well as source it there could be a big problem. How would the supply know if another supply was parallel with it or a battery instead of another supply? If the battery voltage was higher than the supply would it burn out the supply?
Just wondering.
