AC also has some useful properties, such as being able to convert voltage levels with a single component (a transformer), which is why AC was chosen as the primary means to transmit electricity over long distances. Most homes are wired for AC, so if you plan to connect your Tardis music box project to an outlet, you will need to convert AC to DC. However, it is important to understand some AC concepts. Most of the digital electronics that you build will use DC. The voltage in AC circuits also periodically reverses because the current changes direction. Electric charge in alternating current (AC), on the other hand, changes direction periodically.
In direct current (DC), the electric charge (current) only flows in one direction. The latter are also known as star connectors or X connectors.Where did the Australian rock band AC/DC get their name from? Why, Alternating Current and Direct Current, of course! Both AC and DC describe types of current flow in a circuit. These universal power adapters are compatible with multiple voltages in a range - for example, 100-240 volts - and some even have different sized plugs. However, certain models are intended to be used as replacement chargers for a variety of devices.
Most AC/ DC adapters are not universal and can only be used to power compatible devices. For example, the standard British power plug is different from the power plug used in Europe and different from the standard American plug. The AC/DC converters also have a variety of plugs for different outlet designs. Like most electrical devices, AC adapters are built to be compatible with different levels of power, usually expressed in volts. The power cord then feeds this power from the adapter to the device to charge its battery or to run it. This takes AC power from the power source and converts it to DC power at the voltage required by the device. DC is used to transmit electricity along electrical towers and also to power telecommunications equipment, vehicle batteries, and electrical equipment with rechargeable batteries.ĪC to DC adapters typically have a four-sided central unit that contains power switching circuitry. In contrast, direct current does not change direction. This is the format used to provide utility power. AC repeatedly changes direction, alternating between positive and negative terminals within a circuit. How does AC to DC Adapter Work?ĪC and DC are electrical formats. Because plug ratings and types are not universal, AC adapters can only be used with devices that have the same requirements and connectors. The AC/ DC converter then converts the power to the DC that the computer uses, as well as a second power cord that plugs into the computer.Įach AC/ DC adapter has a specific power rating, measured in volts or watts, that it can handle and output to electronics. As shown, the AC adapter consists of a central unit that draws power from an AC outlet. AC to DC adapters help reduce the size of laptops by alleviating the need for standard-sized power supplies. What is AC/ DC Adapter?Īlso known as an AC/ DC adapter, AC converter, or charger, an AC adapter is an external power source for devices that run on batteries or have no other power source. AC to DC power adapters are widely used in security cameras, set-top boxes, routers, light bars, massagers and other equipment.ĪC/ DC adapter rated voltage are optional, good flexibility, fast charging speed, environmental protection, non-toxicity and durability, which ensures that you will find the optimal product for your needs. AC/ DC adapter are used both with equipment with no other source of power and with battery-powered equipment, where the supply, when plugged in, can sometimes charge the battery in addition to powering the equipment. 5V/ 6V/ 7.5V/ 9V/ 12V/ 15V/24V AC to DC wall adapter and 5V/ 9V/ 12V/ 15V/ 24V/ 36V/ 48V AC to DC desktop adapter are provides. Low price ATO AC to DC converter for sale. When the AC adapter supplies power to a battery-powered device, it is also accurate to describe it as a charger. An AC/ DC adapter is an external power supply that converts alternating current (AC) from a wall/desk outlet to a direct current (DC) needed by an electronic device.
