DC power cable how to connect?

One, dc power outlet wiring

Brown is positive, black is negative. Or the center of the jack is positive, the socket is negative.


Second, the DC low voltage power plug typical connection

DC low-voltage power plug is a typical connection jacket grounding, the core connected to the power input. As  for the termination of the positive pole is determined by the device  circuit, the vast majority of the current circuit is NPN polar  components based on the main circuit! The circuit is the common power  supply for the ground, so these electrical equipment DC The interface is negative for the ground, so the power plug of the  jacket should be connected to the negative power supply! Core connected  to the cathode.


Third, DC socket applications
