12V power supplies (or 12VDC power supplies) are one of the most common power supplies in use today. In general, a 12VDC output is obtained from a 120VAC or 240VAC input using a combination of transformers, diodes and transistors.

AC, DC and Electrical Signals. ... For example: a 12V AC power supply has an alternating voltage (which will make an alternating current flow). An electrical signalis a voltage or current which conveys information, usually it means a voltage. The term can be used for any voltage or current in a circuit.
