Power Supply Unit products for sale online in Zambia

A power supply unit (PSU) converts mains AC to low-voltage regulated DC power for the internal components of a computer. Modern personal computers universally use switched-mode power supplies. Some power supplies have a manual switch for selecting input voltage, while others automatically adapt to the mains voltage.

A rectifier that converts AC (alternating current) into DC. A filter that smooths out the DC (direct current) coming from a rectifier. A transformer that controls the incoming voltage by stepping it up or down.

The source power may come from the electric power grid, such as an electrical outlet, energy storage devices such as batteries or fuel cells, generators or alternators, solar power converters, or another power supply.

A power supply is an electrical device that offers electric power to an electrical load such as laptop computer, server, or other electronic devices. The main function of a power supply is to convert electric current from a source to the correct voltage, current, and frequency to power the load.

A power supply takes the AC from the wall outlet, converts it to unregulated DC, and reduces the voltage using an input power transformer, typically stepping it down to the voltage required by the load. For safety reasons, the transformer also separates the output power supply from the mains input.

The purpose of a mains power supply is to convert the power delivered to its input by the sinusoidally alternating mains electricity supply into power available at its output in the form of a smooth and constant direct voltage. The main functions of a power supply include the following: Convert AC to DC. Provide DC voltage to the motherboard, adapters, and peripheral devices. Provide cooling and facilitate air flow through the case.

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.

Often customers confuse transformers and power supplies when they are searching for one or the other. These two technologies are related, but are completely different in their applications.

Power Supply

Electrical outlet, energy storage device such as batteries, fuel cells, generator, solar power converters are generally known as power sources. Power supply is classified into different categories

AC-DC Configurable Power Supply Modules are the circuit board portion of a configurable device that converts an alternating current input into a direct current output with voltages ranging from 2.5 V to 48 V, current from 2.5 A to 53 A, and a power maximum of 33 W to 600 W.
