What is an AC/DC Power Supply?

An AC/DC Power Supply converts AC power to DC Power. In other words, an AC-DC Power Supply is a device that converts one form of electrical power to another desired form and voltage. This typically involves converting 120 or 240 volts AC supplied by a utility company to a well-regulated lower DC voltage for electrical devices.
