greetings companions. I clarify that they are 12 volt regulators, I did this because in my opinion the partner ignored when answering, if the partner responds if you can here are the Datasheet to look at. On my part I did not open another answer. As for the negative vote of the partner 7pk2 for the partner who made the consultation, I do not share it, I think I should have more criteria to rate their classmates.
