It has a wide input voltage range of 6-18V and output power of 120W. It has a high efficiency of up to 88%, low ripple, and low EMI. The design of the converter is highly flexible and allows for easy installation and operation.<2>Application fieldVSUU-120-T515A is suitable for a wide range of applications, such as industrial automation, security systems, medical instruments, network systems, and automotive electronics. It can be used in applications where a stable and reliable power supply is required.<3>Working PrincipleVSUU-120-T515A uses a synchronous rectification method for voltage conversion. The input voltage is first converted to high voltage DC by a PFC stage, which gives it the power factor correction capability. This high voltage is then processed through a DC-DC converter to generate the desired output voltage. The main components of the converter are a PFC stage, a full bridge rectifier, a DC-DC converter, and an EMI filter.The PFC stage is used to convert the AC input voltage into a DC voltage with a high power factor. The full bridge rectifier is then used to convert the DC input voltage into a stable DC output voltage. The DC-DC converter is used to further convert the output DC voltage into the desired DC level. Finally, an EMI filter is used to reduce the level of electromagnetic interference generated by the converter.<4>Conclusion The VSUU-120-T515A is an AC/DC converter that provides reliable, cost-effective solutions for low voltage applications. It has an impressive efficiency, low ripple and low EMI levels, making it suitable for a variety of applications. It is capable of providing a stable and reliable power supply and is easy to install and operate.
