ActiveComponents for low-voltage surge protective devices－Part 351:Performance requirements and test methods for telecommunications and signalling network surge isolation transformers (SIT)
低压电涌保护器元件 第351部分：电信和信号网络的电涌隔离变压器（SIT）的性能要求和试验方法
Application Summary AI generated
This standard specifies the performance requirements and test methods for surge isolation transformers (SITs) used in telecommunications and signalling networks. It ensures these components can effectively isolate and protect sensitive communication equipment from voltage surges and transients in low-voltage systems. The standard is applied by manufacturers and testing laboratories for design verification and compliance certification of SITs in telecom infrastructure, data networks, and industrial control signalling circuits.
