详细介绍

莱姆200A--600A PCB板安装电流传感器

LEM

带来了一个额外的引脚，在输出中的应用程序更加灵活。此引脚提供的ASIC然后可以输送到一个A / D转换器的参考的内部参考电压（模拟数字）这个额外的引脚也可接收内部参考（从2到2.8 V）的DSP（数字信号处理器）或A / D转换器中常用的电力电子技术，允许参考温度漂移消除。当标准型号的机械固定到PCB，SP2模型固定在PCB由于4个额外的引脚焊接。在这两种情况下，次级连接销将PCB焊接。

§ Telecom applications

· European Directive EMC 89 / 336 / EEC: CE Marking

· Low voltage directive 72/23/EEC

· Safety IEC 61010-1

Remarks:

HTFS brings an additional pin, at the output for more flexibility in applications. This pin provides access to the internal voltage reference of the ASIC which can then be fed to the reference of an A/D converter (Analog Digital) This extra pin can also receive the internal reference (from 2 to 2.8 V) of the DSP (Digital Signal Processor) or A/D converters commonly used in Power Electronics, allowing cancellation of the reference temperature drift. When the standard models are mechanically fixed to the PCB, the SP2 models are fixed to the PCB thanks to 4 additional pins to be soldered. In both cases, secondary connections are pins to be PCB soldered.
