【应用】万可推出模块化能源数据采集方案助力能源效率提升，无需编程知识即可实现能源数据管理
万可（WAGO）推出模块化能源数据采集方案, 可轻松实现效能提升。适于多种应用的标准解决方案，无需编程知识即可实现能源数据管理 。对于模块化能源数据采集，采用开放式且灵活的系统，安装简便并可扩展。
开关电源直流电流采样用什么芯片有推荐吗？要求精度要高，范围要大！而且是高边采样，最好能把电压一起采样。电压最好能到48伏
如果要求电流精度很高，采用接触式测量，推荐是viking品牌的采样电阻+SI8921芯片。当然也可以使用电流互感器，推荐使用Weidmueller（魏德米勒）推出KCMA 30-250-1-02VA-1，可以测量250A，工作电压最大值为0.72kV。如果要求精度不是很高，也可以使用迈来芯品牌的霍尔电流传感器MLX91210，目前这款芯片只能测量到±50A的电流，精度可以达到2%。
【产品】适合装在汇流排上的拔插式电流互感器，初级电流分别为1200A、1500A
Weidmuller（魏德米勒）推出四款拔插式电流互感器，具有优异的绝缘性能，绝缘等级均为E，均符合RoHS标准，是环境友好型器件，主要用于智能电网、计量系统等领域，尤其适合装在汇流排上。也适用于软导线和硬导线的接线方案, 方便省时。耐冲击、抗震, 机械保持力高，分别净重999g、1000g、1g、1g。
