AC/DC desktop, wall adapters are on the market with different shapes, sizes, output voltage, output power, and operating frequency. They are used in applications from home charging, computers, instruments, LED lights, and industrial machinery to telecom and medical equipment. In this article we will discuss the SWM6-9-EH-MUB application field and working principle.

SWM6-9-EH-MUB is a DC wall adapter with 6W input power and 9W output power. It has a wide operating temperature range of -20°C to 70°C and an automatic thermal shutdown when over-temperature occurs. It has an IEC320-C6 Jack input port and a DC output connector. The output voltage range is from 4.75 to 17.75V DC. The working frequency is between 50 and 60 Hz.

SWM6-9-EH-MUB is an ideal replacement since it has higher power efficiency compared to traditional AC/DC adapters. This makes the corresponding equipment have a longer operating time. The EMC design meets the IEC 61000-3-2, IEC 61000-3-3, and EN55015, and is qualified by the international safety standards. It also has complete isolation for the input and output which makes it good for applications in medical equipment.

SWM6-9-EH-MUB can be used in numerous applications. It is suitable for smart phones, tablets, broadband terminals, routers, surveillance cameras, and etc. Furthermore, it can be used in appliance controllers, car chargers, LED lights, portable scanners and more. It is ideal for medical applications such as lab instruments, health care products, and medical devices.

The working principle of the SWM6-9-EH-MUB is simple. The AC input is first passed through a rectifier to form a DC input. The input is then converted to the desired voltage level by the switching regulator using a power semiconductor switch. The output is regulated with feedback and compensation components. The power factor correction is then used to increase the power supply efficiency and reduce the harmonic distortion.

In conclusion, the SWM6-9-EH-MUB is a DC wall adapter that is suitable for a wide range applications from home charging, computers, instruments, and LED lights, to medical equipment. It has higher power efficiency than traditional adapters, is qualified by the international safety standards, and has complete isolation for the input and output. Its working principle consists of a rectifier to form a DC input, a switching regulator to convert the input to the desired voltage level, and power factor correction to increase efficiency and reduce harmonic distortion.
