AC-DC Power Supplies
AC DC Power supplies are a device that supplies electric power to an electrical load. AC stands for Alternating Current and DC stands for Direct Current. DC Current flows only in one direction, while AC can reverse direction. Power supplies are used to convert the current from a source to the correct voltage, current, and frequency needed to power. Power supplies are used to limit the current to safe levels, shutting off the current due to electrical fault, prevent voltage surges, and storing energy.
