OWA-120U-42

AC DC Desktop, Wall Adapters

The OWA-120U-42 power adapter is an AC/DC adapter designed for desktop and wall applications. This adapter is also referred to as a wall wart, and is used for powering devices such as laptops, consumer electronics, medical equipment, and other appliances. This model is a 120W (42A) power adapter with a wide adjustable AC input voltage range from 9-39V. It is a highly reliable and compact solution designed for use in a variety of applications, including automotive, railway, and industrial applications.

The OWA-120U-42 AC/DC adapter is designed to provide a high quality and reliable source of power for various electronic equipment. The adapter is highly efficient as it has low transmission losses. This efficiency reduces the energy consumption, thereby reducing the overall cost of the end user. The OWA-120U-42 also features protections against short-circuit, out voltage, overload, over temperature, input over voltage, and input reverse polarity.

The OWA-120U-42 is designed with an EMI filter, which helps to reduce electromagnetic interference and provide a cleaner sound from the audio source. This feature is also beneficial for various medical applications, where electronic interference can sometimes interfere with patient treatment. This power adapter also features a low standby power consumption, which reduces its overall energy cost.

The working principle of the OWA-120U-42 AC/DC adapter is relatively simple. The AC voltage input is converted into a regulated DC output. This is done through a combination of a step-down transformer, bridge rectifier, and a voltage regulator. The transformer reduces the input voltage to a lower value, while the bridge rectifier converts the AC input into a DC output. The voltage regulator then ensures that the DC output is constant and that the output voltage is within an acceptable range.

The OWA-120U-42 AC/DC adapter is a reliable and efficient way to power various electronic devices. It provides a continuous and consistent source of power that is cost-efficient and safe. This adapter is ideal for applications such as automotive, railway, and industrial applications, as well as applications in the consumer electronics, medical equipment, and other industries.
