Power Supply products for sale online in Zambia

Power supplies receive power from an electrical outlet and convert the current from AC (alternating current) to DC (direct current). They may also convert a different form of energy – such as solar or mechanical into electrical energy. Here, you will find a wide variety of power supplies including, DC inverters, solar panels, batteries, charge controllers, portable solar systems, static solar power UPS systems and more. Brands available include but are not limited to Su-Kam, eMax, cMax, PylonTech, JFY, Izzy Power and more. If in doubt on the best power supply for your energy requirement, please feel free to enquire. Knowledgeable electrical engineers are always ready to recommend the best products based on your power needs. Buy with confidence, all products purchased are of the highest quality and come with a warranty.

There are three subsets of regulated power supplies: linear, switched, and battery-based. Of the three basic regulated power supply designs, linear is the least complicated system, but switched and battery power have their advantages.

Two types of power supplies exist, DC-DC and AC-DC.

Types of computer power supply

There are 3 types of power supply in common use: AT Power Supply - used in very old PCs. ATX Power Supply - still used in some PCs. ATX-2 Power Supply - commonly in use today.

Purposes of a Power Supply

• Convert AC to DC.
• Provide DC voltage to the motherboard, adapters, and peripheral devices.
• Provide cooling and facilitate air flow through the case.

PC Power Supplies Work

• 3.3 volts.
• 5 volts.
• 12 volts.

Power Supply Circuits

• Unregulated. An unregulated power supply is the most rudimentary type, consisting of a transformer, rectifier, and low-pass filter.
• Linear regulated.
• Switching.
• Ripple regulated.

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.

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.

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.

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.

Direct current (DC) occurs when the current flows in one constant direction. It usually comes from batteries, solar cells, or from AC/DC converters. DC is the preferred type of power for electronic devices. Alternating current (AC) occurs when the electric current periodically inverts its direction.

The DC power supply is a device that creates and supplies a stable Direct Current (DC) from the AC power supply of the outlet. It is used as a power source to run electronic circuits or to check electronic devices.
