AC DC Desktop, Wall Adapters

The WSU050-2000 application field and working principle is based around the use of AC DC adapters. These adapters, which are sometimes referred to as “Wall Adapters”, are used for powering electronic equipment when a direct connection to a wall outlet is not possible. The adapter takes AC voltage from a wall outlet and converts it to DC at the desired voltage, providing an alternate means of supplying voltage to the electronic equipment.

With desktop computers, the AC DC adapter is designed to take 120 volt AC from either a wall outlet or a transformer and convert it to the appropriate DC voltage, typically +12 volt, +5 volt, or +3.3 volt. The DC voltage is then used to power the positive and negative rails of the computer’s motherboard.

Wall Adapter Working Principles

Wall Adapters essentially operate in the same manner as a standard AC/DC adapter, except that instead of taking AC from a wall outlet, it takes the voltage from either a transformer or directly from a battery. Unlike the AC/DC adapter, the Wall Adapter does not convert the voltage to DC, instead it adds the appropriate voltage boost to get the desired DC voltage.

For example, if the voltage coming from the transformer is 18 volts, the wall adapter can be adjusted or “boosted” to bring it up to the desired voltage for powering the electronic device.

Advantages of Wall Adapters

One of the key advantages of using wall adapters is that they are less expensive than AC/DC adapters. Additionally, wall adapters are less bulky and easier to transport than AC/DC adapters. The lower cost and portability make wall adapters particularly attractive for applications where costs or portability are factors.

Additionally, wall adapters are easier to adjust, allowing the user to more precisely adjust the voltage output to the device being powered. This can be beneficial in cases where the exact voltage of the device being powered is not known or can vary.

Disadvantages of Wall Adapters

The disadvantages of using wall adapters are that they require more effort to install and maintain than AC/DC adapters. Additionally, wall adapters may not be able to produce the required DC voltage for high power devices and therefore may not be suitable for such applications. Finally, there may be compatibility issues between some wall adapters and certain devices being powered, depending on the type of adapter being used.

Conclusion

In summary, the WSU050-2000 application field and working principle is based on the use of AC DC adapters. Wall adapters are a good alternative to AC/DC adapters in cases where cost, portability, or adjustable voltage output are desirable. However, they may not be suitable for high power applications nor may they be compatible with all devices.
