AC/DC Desktop, Wall Adapters such as OWA-60U-42 are widely used and make great contributions to the AC-DC power industry. This article will explore its application field and working principle.

Applications

The OWA-60U-42 desktop adapter is invaluable due to its unique combination of a wide input voltage range (from 85~265V AC), output power up to 60 watts and slim and compact dimensions. This greatly reduces the need for stock control of multiple models for different input voltage ranges, and allows the OWA-60U-42 to be used in a number of different applications:

• Domestic applications, such as connecting to mains power to charge phones and laptops, or to power medical equipment.
• Industrial applications like powering telecommunication cabinets, industrial equipment and control panels.
• Security applications, such as CCTV power supplies.

In addition, OWA-60U-42 desktop adapters are also designed with high efficiency, low no-load power consumption, and three levels of protection against short-circuit, overload, and over-voltage. This is to make them safer to use, and to prevent damage to the equipment.

Working Principle

The OWA-60U-42 desktop adapter is a class II switching adapter, which internally consists of a bridge rectifier, an AC/DC SMPS switching power supply, and an output filter circuit. As shown in the diagram below:

When the adapter is plugged into the mains, AC voltage is supplied to the rectifier, which converts it to DC voltage. This is then fed to the SMPS power supply, which is used to create the output voltage. Finally, the output filter circuit is used to remove both the ripple voltage and noise generated by the SMPS, which ensures a clean and pure output.

The OWA-60U-42 desktop adapter also features thermal shutdown technology, which helps to protect the device against excessive temperature. When the adapter temperature rises too high (usually due to high load), the thermal sensor trips, which in turn stops the power supply switching action, reducing the heat generated and thus protecting the device.

Conclusion

As can be seen, the OWA-60U-42 AC-DC desktop adapter is a great power supply solution for both domestic and industrial applications. It has a wide input range, high power delivery, and is designed with safety and reliability in mind. It has a variety of features which make it an invaluable device for powering a wide range of devices.
