Greetings, greetings, greetings!
I have an AC/DC power converter that takes 100-240VAC input and outputs 12VDC. Works great, no problem. However, that are times when it would have been nice to be able to use an available DC power source. Essentially bypassing the AC/DC converter and supplying the 12VDC from an external source. When running from 12VDC external power, the AC plug would not be connected. Intuition says that I can't just introduce the external DC power directly to the board, or can I? What would happen to the AC/DC converter if it sees 12VDC and no AC power? Will it act as a DC/AC converter?
I'm not looking to redundify (not a word, I know) the power. I only trying to figure out how to introduce an external 12VDC power source.
