The WS-12-250-DC needs POSITIVE 9V to 72V - You can NOT use NEGATIVE voltage with the WS-12-250-DC
If you have a NEGATIVE DC site we only have one model that works with NEGATIVE voltage which is the WS-26-400-IDC which will use POSITIVE or NEGATIVE 36V to 72V DC input
Using any other model than our WS-26-400-IDC with NEGATIVE DC input will blow the switch and the device your are powering.
