First, let’s understand why we need a power supply. Desktops, laptops, phones, and other electronics simply can’t function using the kind of electricity that we usually get from the wall socket, which is AC power. Electronicsrequire Direct Current (DC)instead ofAlternating Current (AC)to f...
what is a power switch? learn more what is a power switch? a power switch is a device that allows you to turn an electronic device on or off. it's like a toggle switch that controls the flow of electrical power to the device. when the switch is in the "on" position, it completes...

A rocker switch to turn the power supply on and off.On the front of the power supply, which is not visible unless the computer is opened, you find several cables. These cables connect to the computer motherboard and other internal components. With an ATX (Advanced Technology eXtended) mother...
The buck converter is an essential part of the switching mode power supply. Giving it much higher power efficiency than a linear power supply. For example, we want to use a 3.7V 3W LED with an AC adapter of 12V 0.5A. But the voltage level is too high. So we have to lower the volt...
An uninterruptible power supply (UPS) is a device that allows a computer to keep running for at least a short time when incoming power is interrupted. Provided utility power is flowing, it also replenishes and maintains energy storage.
A: There is an adjustable switch on the back of the power supply. If the input voltage in your area is 110V, please turn the switch to 115V to use it. If the input voltage in your area is 220V, please turn the switch to 230V to use it. The factory default value of power input...
