A power supply is an electrical device that supplies electric power to an electrical load. The main purpose of a power supply is to convert electric current from a source to the correct voltage, current, and frequency to power the load. As a result, power supplies are sometimes referred to as electric power converters.
Very small power supply systems typically use lead acid batteries to provide both the energy storage and a central DC connection point for the various loads and generators. Nominal battery voltages are usually in the range 12 – 120 V DC.
