【应用】硕凯国产压敏电阻SC1812-90CSMD和瞬态电压抑制器阵列SLVU2.8-8在交换机中的应用
交换机在使用中经常会遇到意外的电压瞬变和浪涌,从而导致内部电子器件的损坏。电压的瞬变和浪涌无处不在,电网、雷击、爆破,就连人在地毯上行走都会产生上万伏的静电感应电压,这些,都是变频器控制端口和通信端口的隐形危害源。因此,为了提高交换机的可靠性就必须对电压瞬变和浪涌采取防护措施。
在作为局域网的主要连接设备,以太网交换机成为应用普及最快的网络设备之一。针对以太网口的浪涌防护,硕凯电子给出如下解决方案:
方案说明及注意事项
1、此方案为以太网交换机千兆以太网口过压保护方案。
2、可以通过IEC61000-4-5标准波形Surge测试及IEC41000-4-2标准波形Discharge测试。
该方案中采用硕凯电子的压敏电阻SC1812-90CSMD和瞬态电压抑制器阵列SLVU2.8-8。参数如下:
一、SC1812-90CSMD
主要优势:1、容值低(<1pf),有助于保持信号完整性,并将数据丢失率降至最低。;2、体积小,通流量大,满足IEC61000-4-5:10/700US 6KV/150A;1.2/50US&8/20US 2KV/1KA测试要求。测试记录如下:
二、SLVU2.8-8
主要优势:1、具有低电容,有助于保持信号完整性,并将数据丢失率降至最低。2、满足IEC 61000-4-2的最高标准(CONTACT DISCHARGE :8KV;AIR DISCHARGE:15KV),在安装和使用期间为设备提供最大的可靠性。测试记录如下:
硕凯电子是专业的防雷元器件生产商,防护方案设计专家,所有元器件都具有相关UL证书,REACH/ROHS有害物质检测证书,性能稳定可靠。欢迎通过世强选型测试。
