【应用】双通道数字隔离器NSI8221W1-DSWR用在三相多功能电力仪表中,设备经UL1577安全认证
三相多功能电力仪表主要面向民用建筑、工业企业和基础设施等领域的电力监控、电能计量、能源管理等智能化、信息化应用,为后台系统提供符合国际标准的实时、准确的电力测量、计量和电能质量数据信息,以满足电力监控、能源管理、负荷控制及运维管理的需求。
三相多功能电力仪表产品框图
在产品设计需求中,通讯接口采用RS-485,接口需要5KV的隔离,而且产品在国内和国外都有销售,需要认证齐全,重点要有UL认证,隔离浪涌电压要能到10KV。
纳芯微的NSI8221W1-DSWR是双通道数字隔离器,一正一反,可以实现RS-485的隔离,而且它支持绝缘耐受电压5kVrms,隔离等级高,能让产品更可靠。NSI8221W1-DSWR共模瞬态抗扰度(CMTI)高达250kV/μs,隔离浪涌电压大于10kV,能有效防止瞬间浪涌冲击,提高产品安全等级。
设备经UL1577安全认证、CQC认证、CSA认证,可以满足远销国外的要求。电源电压2.5V至5.5V,宽电压范围适合3.3V和5V系统,工作温度-40℃~125℃,更宽的工作温度范围使产品满足各种工业现场的应用。另外功耗1.5mA/ch(1 Mbps)降低了系统的功耗,传播延迟小于15ns,速率传输率150Mbps,实现了高速传输使后台能实时看到上传数据。

【选型】国产双通道数字隔离器NSI8121N1Q与ADI的ADUM1201ARZ-RL7参数性能对比分析
为了防止各模块之间因为压差及电流差值过大造成相互影响,一般通信接口会使用隔离器件进行信号电平转换。隔离方式会有容隔、磁隔及光隔。现介绍一款纳芯微电子的双通道数字隔离器NSI8121N1Q,其功能与ADI的磁性隔离芯片ADUM1201ARZ-RL7较相似。
