| Your DC voltage source can either be used as a positive or negative source by simply reversing poles as long as there is one ground reference.
In other words, a negative supply measured from point A to B is simply positive when measured from B to A. So by reversing polarity you should be able to run your device-----unless I misunderstood your question.  |

|
| Hi guys....
I have a question related to powering up a circuit I have .... Actually it is the circuit of Vehicle tracking unit.... it is capable of Input voltage of 9 - 28 VDC... My problem is that: the power source I have provides me with negative voltage ( or I how only the negative voltage available or reachable)... now my question is: How can I power up my tracking unit using this negtive voltage source,,, what are the possible options that can be done?? thanks for ur help  |
