AC/DC converters are essential components in many modern electronic devices. In order to ensure the safe and reliable operation of the device, a qualified AC/DC converter is necessary. SWF100P-48-LC-R is a qualified AC/DC converter, its application field and working principle will be discussed in the following.

SWF100P-48-LC-R is an AC/DC converter with an input voltage of 85~264VAC, output voltage of 5V to 24VDC and output current of 10A. It also has a variety of industrial certifications, such as UL, CE, FCC and ErP. It is suitable for a wide range of applications in industrial, communications, automotive and consumer markets, such as PLC control systems, AC servo drives, UPS systems and laboratory power supply.

Its built-in active PFC (Power Factor Correction) circuit helps to maintain high power factor, reduce harmonic distortion in the output current waveform, and reduce consumption of equivalent switching frequency. With its wide input voltage window, its output power can still remain stable when the input voltage fluctuates. And its built-in protection function can also protect the device from lightning strikes, overcurrent, overload, short circuit and overtemperature.

SWF100P-48-LC-R utilizes low frequency isolation transformer technology to achieve the above mentioned advantages. Its working principle can be described as consisting of three main parts: input, bridge rectifier, and output. The input part of the converter contains a galvanic isolation transformer, with the primary side connected to the AC power supply and the secondary side connected to the rectifier bridge to form the input. The bridge rectifier can convert the AC input to pulsating DC and then remove the ripple by the capacitor. The output part consists of an LC filter, a regulator and a feedback loop. The filter performs low-pass filtering of the rectified and smoothed input voltage and the regulator adjusts the output voltage such that it maintains stability in case of varying input voltage. The feedback loop adjusts the output voltage based on the feedback signal from the load.

In summary, SWF100P-48-LC-R has a wide range of applications and the advantages of high power factor, wide input voltage window, built-in protection and stability. Its working principle consists of three main parts – input, bridge rectifier, and output. It is a qualified AC/DC converter and is suitable for a wide range of applications in industrial, communications, automotive and consumer markets.
