DC Power Supplies

EZ Digital, Inc. (EZ Digital, Inc.)

Power Supplies deliver electric power to a device or circuit (Electrical Load), usually by stepping down a higher voltage. DC Power Supplies step down the voltage and convert it to DC. For example, 220 VAC to 12 VDC. Every power supply has an input or supply power and converts it by various methods to meet the demand from the electrical load. Power supplies are said to be Regulated by controlling the output voltage or current to a constant value, even if the load demand current or the supply power varies. At the heart of any power supply is a Transformer, which converts the supply power to the output power to the load.
