         Multifunctional power protection modules from UNSEMI are designed for industrial power applications. The module supports up to 3A operating current and 60V input voltage to meet the needs of the vast majority of power applications. In industrial electronic products, the stability and reliability of the power supply is the core to ensure product quality. However, due to the complex and changeable working environment of industrial electronic products, the power system often encounters external interference, such as input voltage misconnection, inrush current shock, abnormal voltage fluctuations, circuit overload and load short circuit. As the power source of electronic products, ensuring the safe, stable and reliable operation of the power supply is the top priority of R & D engineers. Often, designing these protection circuits and verifying their reliability takes a lot of development time. The multifunctional power protection module of UEN Semiconductor integrates these protection functions, simplifies the application circuit design, and provides a wealth of protection characteristics, effectively improves the input and output protection level of the power supply, and ensures the long-term stable operation of the power system, thereby extending the service life of the electronic equipment. 

Product Advantage
