FC-SCT2108-200T电流互感器产品概述

FC-SCT2108-200T是方成(FC)推出的表面贴装式电流互感器,专为中功率场景下的高精度电流测量与电气隔离需求设计。产品凭借1:200精准匝数比、5kV(Vrms)高隔离电压及紧凑SMD封装,成为光伏逆变器、充电桩、工业电源等领域的实用选择,平衡测量精度、安全性能与空间效率。

一、产品核心定位与应用场景

FC-SCT2108-200T的核心定位是中功率范围的“安全型高精度电流采样元件”,针对以下典型场景优化:

  • 新能源领域:光伏并网逆变器阵列电流监测、电动汽车充电桩充电电流控制、储能系统(BMS)充放电电流采样;
  • 工业电源:开关电源输出电流保护、UPS不间断电源负载监测;
  • 智能计量:智能电表/电能监测模块电流采样;
  • 小型化设备:便携式充电桩、微型逆变器等对体积敏感的终端。

其设计兼顾“安全隔离”与“测量精度”,解决高低压电路干扰问题,保证电流信号线性传输。

二、关键电气参数详解

1. 电流转换与精度

  • 匝数比:1:200(精准匹配,误差≤1%);
  • 额定输入电流:50A(持续工作安全范围);
  • 转换逻辑:初级输入50A时,次级输出0.25A电流——串联10Ω采样电阻可得到2.5V电压信号,直接适配多数ADC模块,无需额外放大电路。

2. 安全隔离性能

  • 隔离电压:5kV(Vrms,交流有效值);
  • 意义:满足IEC 61010安全标准,有效隔离初级高压电路(如光伏阵列、充电桩高压端)与次级控制电路,防止高压击穿损坏模块,保护操作人员安全。

3. 损耗与线性度

  • 初级侧内阻(最大):0.5mΩ;
    优势:电流损耗极小(50A时功率仅1.25W),持续工作发热低,可靠性高;
  • 次级侧电感:17.5mH;
    优势:保证50/60Hz工频及1kHz以内频率范围的电流线性度≤0.5%,避免信号失真;
  • 次级侧内阻(最大):12Ω;
    提示:采样电路设计需预留补偿空间,确保输出信号准确。

三、封装与物理特性

FC-SCT2108-200T采用SMD-6P表面贴装封装,核心物理参数:

  • 尺寸:20.5mm(长)×12.8mm(宽)×5.0mm(高,典型值);
  • 引脚:6引脚设计,符合IPC标准,适配自动化贴装生产线;
  • 耐温:支持无铅回流焊(峰值温度260℃/10秒),符合RoHS环保要求。

封装优势

  1. 体积紧凑:比传统插件式互感器缩小约30%,节省PCB布局空间,适合小型化终端;
  2. 自动化适配:高速贴装降低人工成本,减少焊接不良率;
  3. 安装稳定:6引脚增强焊接强度,抗振动能力强,适配工业环境。

四、核心优势与价值

FC-SCT2108-200T相比同类产品,具备以下差异化优势:

  1. 高安全隔离:5kV隔离电压远高于行业常规3kV标准,满足新能源、工业领域严苛安全要求;
  2. 高精度转换:匝数比精准,初级内阻小损耗低,额定电流范围内采样误差≤0.5%;
  3. 低损耗设计:初级内阻仅0.5mΩ,无需额外散热设计,简化终端结构;
  4. 宽适配性:10-50A持续工作范围,短期过载可达75A/10秒,适配负载波动;
  5. 成本效益:SMD封装降低生产效率成本,性能满足多数场景需求,无需高端传感器替代。

五、典型应用方案示例

以光伏并网逆变器为例,FC-SCT2108-200T的应用逻辑:

  • 初级串联光伏阵列输出端(输入电流10-50A);
  • 次级串联10Ω采样电阻,输出2.5V(50A时)电压信号;
  • 信号传输至MCU的ADC模块,实现最大功率点跟踪(MPPT)电流反馈,同时5kV隔离保护控制电路免受光伏高压冲击。

总结

FC-SCT2108-200T精准平衡“安全隔离、测量精度、体积效率”三大核心需求,适用于新能源、工业电源、智能计量等中功率场景。其高隔离电压、低损耗设计及自动化适配的SMD封装,能帮助终端产品提升安全性能、简化结构设计并降低生产成本,是中功率电流测量领域的高性价比选择。
