什么是IEC61000-4-5？
该测试不是直接雷击测试，而是模拟测试附近受雷击影响感应的浪涌电压／电流。测试还包括电源系统开关（电容开关、配电系统开／关、负载变化、短路等）引起的开合浪涌。
IEC61000-4-2规定的ESD浪涌几乎是所有电子设备都会遇到的问题。而IEC61000-4-5模拟测试提出的问题也适用于工业设备及感性负载通信线路、电源线和控制线。
因为这些浪涌通常主要是由于感应引起的。
IEC610004-5提供了模拟这些浪涌的模型，用于检查设备是否具备浪涌承受能力。
根据设备安装位置，标准定义了5个类别等级（浪涌控制等级）（施加电压：25V至4kV）。
我们提供了符合IEC61000-4-5标准的器件，以支持浪涌防护措施。
