The Internet of Things (IoT) industry is growing rapidly with the IoTcommunications technologyrespond in singingVarious agreementsThe development of IoT, the rapid increase of related IoT terminal products, so that the whole ecosystem is getting healthier and healthier; but stability and reliability has always been the most important concern of all participants in the IoT industry, especially the industrial IoT enterprise-level applications, some simple errors can lead to the whole system problems, and generate great remedial costs. Therefore, in addition to the signal isolation protection shown in the figure below, the Internet of Things infrastructure equipment is inseparable from the power supply, so the power supply has become the most core and critical components affecting the stability and reliability of the entire system, and the protection of the power supply is also critical.
World Power Technology based on a variety of communication protocols and sensors to create the basis of the Internet of Things products, in the development process of the power supply selection and demand for more and more stringent, therefore, with the power supply suppliers to create a power supply module in line with the Internet of Things industry, 1W power supply module products is the first mass production of the module we launched, we will follow up with the launch of more series of products.In addition to standard products, we can also assist you in customizing the products you need.Please feel free to contact us.

Typical Circuit
- If further reduction of input and output ripple is required, a capacitive filter network C1 can be connected to the input and output.
- Care should be taken to use a suitable filter capacitor, 4.7uF/50V is recommended, if the capacitor is too large, it is likely to cause starting problems.
- For each output, the recommended capacitive load C2 value for safe and reliable operation is listed in the selection manual.
