RSP20-168

  • 针对 RIA12 和 NF F01-510 瞬变的浪涌保护器(电压钳位)
  • 输出电压随输入电压变化,直至达到钳位电压。
  • 最大负载为 20 W、150 W 或 300 W。
  • 工作温度为 -40°C 至 +95°C
  • 电路板安装模块

RSPxxx-168 浪涌保护器模块为 DC/DC 转换器提供保护,防止其受到铁路应用中高达 385 VDC 的瞬态过电压的破坏。

输出电压在 40-165VDC 范围内会对输入电压进行跟踪,超过此范围后,输出电压被钳位至 168 VDC。

RSP20-168 是一款 DIP24 模块,插入简单,可与 RP08-110xxSAW、RP08-110xxDAW、RP20-110xxSFR 和 RP20-110xxDFR 转换器系列的输入进行串联,使其符合 RIA12 和 NF F 01-510 的浪涌抗扰度规范要求。

RSP150-168 模块采用电路板安装,插入简单,可与 RP40-110xxSFR、RP75H-110xxSRW、RP90Q-110xxSRW、RPA100H-110xxSRUW、RPA120H-110xxSRW 和 RP120Q-110xxSRW 转换器系列的输入串联,使其符合 RIA12 和 NF F 01-510 的浪涌抗扰度规范要求。

RSP300-168 模块采用电路板安装,插入简单,可与 RP180H-110xxSRW、RPA200H-110xxSRUW 和 RP240H-110xxSRW 转换器系列的输入串联,使其符合 RIA12 和 NF F 01-510 的浪涌抗扰度规范要求。
