The intelligent switchboard integrates multiple power monitoring, automation control, and communication functions, serving as the nerve center of a digital power distribution system. For its dense internal sensor network and communication bus, we offer comprehensive electromagnetic compatibility (EMC) protection and multi-level surge filtering solutions, effectively suppressing transient interference generated by the high-voltage environment within the cabinet. These protection technologies ensure the accuracy of monitoring data acquisition and guarantee that the core controller can still achieve intelligent scheduling and status diagnosis even in harsh electrical noise environments, contributing to the construction of a transparent and efficient power distribution network.
