Alternating current (AC) power is the power supply that is supplied from the power plant to the switchboards and outlets in homes, factories, and buildings. One of the features of AC power is switching the positive and negative sides in cycles of 50 Hz and 60 Hz.
Products sold as AC Power Sources (AC power supplies) are AC to AC converters, used to supply different voltages and frequencies in different regions, stable voltage AC power supply, and to test for noise and momentary power loss.
