AC-DC desktop, wall adapters, such as the Vel18US090-EU-JA, are a type of electrical device used to both convert AC current from mains power into a DC current and to provide an additional voltage level so that a device can receive the appropriate current for its individual power needs. This type of adapter can come in various sizes and formats and is typically used when a device requires a slightly different voltage rating than what is available from mains power; supplying the appropriate amount to a device to ensure it is powered correctly.
In order to understand how the the Vel18US090-EU-JA functions, it is necessary to break down the components of its working principle starting with the AC voltage, a typical input voltage accepted by the AC-DC desktop wall adapter. This AC voltage is designed to be compatible with inputs from any location in the world, allowing for a universal application between different regions. This input voltage is then converted from AC to DC via a rectifier, such as a diode bridge. This process is used to protect the device from any potential damage that may come from DC transients by ensuring a constant voltage is supplied. In addition to this, the adapter also includes a set of small coils, a capacitor and a voltage regulator.
The small coils, commonly referred to as chokes, help to filter the current coming from the rectifier, eliminating any high-frequency noise from the AC signal. This not only ensures a clean output, but also prevents any surge or spikes from damaging the device or potentially overheating related components. The capacitor is used to help store energy and ensure that the output voltage is filtered and supplied smoothly. The last crucial component which makes up the Vel18US090-EU-JA, is the voltage regulator, which is used to output a steady, regulated voltage to the device given the varying input, allowing the device to get the unique voltage and power rating necessary to operate.
Given its versatile application and easy installation, the AC-DC desktop wall adapter is an essential device for any electronic application. By understanding the different elements which make up this type of adapter such as the components used and the different types of voltages employed, it is easy to see how these types of adapters can be beneficial in any type of power supply setting.
