Definition For Power Supply

They re like backup power supplies that provide power when the primary psu is disconnected from its regular power source.

Definition for power supply. For example 12 volts is commonly used for drives while 3 3v and 5v are used by the chips and other motherboard components. The power supply then pulls the required amount of electricity and converts the ac current to dc current. What is the meaning of power supply. Power supplies are packaged in different ways and classified accordingly.

A bench power supply is a stand alone desktop unit used in applications such as circuit test and development open frame power supplies have only a partial mechanical enclosure sometimes consisting of only a mounting base. Since power supply units are often victims of power surges and power spikes because it s where the device receives electrical power you can plug the device into a ups or a surge protector. An uninterruptible power supply ups is another type of power supply. It also regulates the voltage to an adequate amount which allows the computer to run.

It receives power from an electrical outlet and converts the current from ac alternating current to dc direct current which is what the computer requires. Not all power supplies however do an adequate voltage regulation job so a computer is always susceptible to large voltage fluctuations. How do you use power supply in a sentence. A computer power supply converts ac into multiple dc voltages.

The power supply converts a 110 115 or 220 230 volt ac alternating current into a steady low voltage dc direct current usable by the computer and rated by the number of watts it generates. Definition what does power supply mean. Abbreviated as ps or p s a power supply or psu power supply unit is a hardware component of a computer that supplies all other components with power. The image shows an antec true 330 a 330 watt.

A power supply is a component that supplies power to at least one electric load. A power supply is a hardware component that supplies power to an electrical device. It also regulates the voltage to eliminate spikes and surges common in most electrical systems. Power supply definition is a device providing power to electronic equipment and sometimes designated a b or c according to its function of heating vacuum tube cathodes causing a flow of electron current in plate circuits or applying a direct voltage in grid circuits.

Typically it converts one type of electrical power to another but it may also convert a a different form of energy such as solar mechanical or chemical into electrical energy.
