AC/DC Desktop, Wall Adapters: OWA-120E-42 Application Field and Working Principle

OWA-120E-42 AC/DC Desktop, Wall Adapters have versatile applicability and are generally used either for desktops or walls in residential, commercial, and industrial environments. This type of power supply is inherently capable of converting 120 volts of AC to 12 volts of DC current, and is also capable of converting some other frequencies of alternating current to the equivalent voltages of direct current. It is designed to emit a low amount of noise to help ensure a calm environment, and also has protection against short circuit and overload.

To understand the application field and working principle of the OWA-120E-42 AC/DC Desktop, Wall Adapters, it is important to start by inspecting the design. It is a single voltage adapter with a current rating of 5 Amperes and an input voltage of 100 to 240 Volts AC. It is designed with an integral power switch and a three-prong design to provide better safety and compatibility with many computers and electronic equipment. Also, on the outside of the adapter are a number of features that aid in its versatility. These features include an output jack, a ground LED, a status LED, and an input jack.

In terms of the working principle, the OWA-120E-42 AC/DC Desktop, Wall Adapter relies on the AC input voltage to convert it to the required DC output voltage. Specifically, the AC input voltage activates a transformer consisting of two circuits – a primary and a secondary. The primary is in charge of converting the AC voltage into the required DC voltage, and the secondary is designed to transmit the converted voltage to the output jack. In addition, the adapter also uses a Flyback diode to ensure that the output voltage is consistent and safe, while the P-Channel MOSFET is responsible for temporarily switching the current flow. And finally, the adapter also utilizes an electronic switch to reset the device should an overload or short-circuit occur.

In conclusion, the OWA-120E-42 AC/DC Desktop, Wall Adapters can be effectively used in a wide variety of applications. Furthermore, by understanding the design and working principle, it can be seen that these adapters possess a number of features to help ensure that the environment is safe and that the output voltage is consistent. Thus, it is important for those looking for a reliable and versatile power supply to consider these adapters for their needs.
