PW172KB1503F01 Datasheet/PDFAC DC Desktop, Wall Adapters
The PW172KB1503F01 is a small and low-profile, off-the-shelf AC DC desktop or wall adapter. This type of adapter is designed to provide regulated DC power without the need for a traditional AC power source, making it ideal for systems that operate on limited power sources.
Application Field
The PW172KB1503F01 is well-suited for many different applications, including low-current industrial, medical, automotive, IT, consumer, and communications applications that require up to 500 Watts. It can be used to power most devices with an input current less than 6A, making it an ideal solution for computer systems, medical equipment, audio and video devices, LED lighting and more.
Working Principle
The PW172KB1503F01 is designed with a full linear topology, which is an advanced type of AC DC switching power supply. This topology ensures more reliable performance and a minimal number of components. When the adapter is first plugged in, a low frequency switching converter is used to convert the alternating current (AC) from the wall plug into direct current (DC). This DC is then converted to the necessary voltage by a ‘high frequency’ converter. This suite of converters is managed by a controller, ensuring smooth, stable delivery of the needed voltage.
The input voltage range of the PW172KB1503F01 is 90 to 264 Vac, and the output voltage range is 3.3 to 15 Vdc. This wide range allows the adapter to be used safely in most applications. The converters come with a low-ripple design, which reduces the noise generated and also protects other components from damage. The PW172KB1503F01 also has adjustable electrical resistance to ensure proper matching of the voltage output with the required loads.
The PW172KB1503F01 is also designed for safety. It features built-in over-temperature and short circuit protection, as well as a fire-retardant plastic shell. It is certified to adhere to the UL, cUL, TUV, and GS safety standards, meaning it is safe to use in most applications.
Conclusion
The PW172KB1503F01 is a small and low-profile AC DC desktop or wall adapter, ideal for low-current industrial, medical, automotive, IT, consumer, and communications applications. It is designed with a full linear topology, featuring adjustable electrical resistance and a low-ripple design for maximum efficiency. For added safety, it is certified to adhere to the UL, cUL, TUV, and GS safety standards.
