【应用】全业电子推出RS485/232防护方案，前端采用通流量大的GDT，泄放大电路
RS485/232走线很长，易有过压现象，且其置于室外，易受雷击和其他线路干扰。在此应用背景下，全业电子推出基于TSS半导体放电管P0080SB和GDT陶瓷气体放电管UN3E5-470LSMD、UN3E6-470MM的RS485/232防护方案，适用于监控/安防系统、门禁系统等。
产品外观
方案说明及注意事项
前端采用通流量大的GDT，泄放大电路
后端采用反应时间快的TVS，残压低，有效保护RS485/232芯片
中间采用电阻做退耦，让前端GDT更容易动作，达到泄放电流作用
本方案满足IEC61000-4-2、GB/T17626.2等静电标准，IEC61000-4-5、GB/T17626.5等浪涌标准
可通过10/700μs（等效内阻400ohm）、1.2/50μs-8/20μs测试，具体防护等级需参考GDT和TVS的通流量
方案应用
监控/安防系统
门禁系统
铁路信号控制灯
智能交通系统
电表/水表/仪器仪表
