In the era of data deluge, data centers, as the cornerstone of the digital economy, have an almost exacting demand for power reliability - 99.999% availability means no more than 5.26 minutes of downtime throughout the year. However, in traditional data center power management solutions, the contact aging, action delay, and arc interference of mechanical relays have become potential risks affecting power quality and equipment lifespan. Especially with the explosive growth of AI computing centers, the kilowatt-level power density per cabinet poses unprecedented challenges to power distribution and control. 

Golden Electrictech has deeply analyzed the development trends of data centers and developed a dedicated solid-state relay solution for key systems such as power distribution, cooling, servers, and security. With its technical advantages of millisecond response, zero contact wear, and ultra-high reliability, it provides silent and solid power protection for the infrastructure of the digital world.
