FC-SCT1090-200T-50A电流互感器产品概述

一、产品定位与核心价值

FC-SCT1090-200T-50A是方成(FC)品牌推出的DIP直插式电流互感器,专为中大功率电气系统的电流检测与保护设计。该产品通过精准匝数比转换,将高压侧大电流信号安全隔离为低压侧易测量的小电流信号,兼具高隔离、低损耗、易集成三大核心优势,广泛适配工业自动化、新能源、电力配电等领域的电流监测需求。

二、核心技术参数深度解析

产品关键参数直接决定应用性能,具体解析如下:

  1. 电流转换特性:采用1:200匝数比设计,初级输入额定电流50A时,次级输出250mA(线性转换关系),无需额外放大即可适配后端采样电路;
  2. 隔离安全能力:额定隔离电压2.5kVrms,满足工业级高压隔离要求,可有效阻断初级侧故障向次级侧扩散;
  3. 损耗与电感特性:
    • 初级侧最大内阻0.8mΩ:额定电流下功率损耗仅约2W,长期工作无过热风险;
    • 次级侧电感20mH+内阻4.5Ω:确保信号响应速度与输出精度,需匹配适当负载电阻(避免负载过大影响线性度);
  4. 封装与额定值:DIP直插封装适配传统PCB工艺,额定输入电流50A覆盖中功率设备(如11kW电机、10kW充电桩)的持续工作需求。

三、关键性能优势

  1. 高安全隔离设计:2.5kVrms隔离电压覆盖多数工业场景的高压防护需求,可避免初级侧(如电机、光伏阵列)的高压击穿次级侧控制电路;
  2. 低损耗高精度转换:极小的初级内阻与稳定的次级电感,确保电流转换失真度<1%(典型值),满足能效分析、过载保护等高精度场景;
  3. 易集成与兼容性:DIP封装无需特殊焊接设备,可直接兼容现有PCB设计;250mA输出适配常见ADC采样、继电器保护电路,降低系统设计难度;
  4. 宽工况适应性:额定50A输入覆盖中功率设备,短期峰值电流(如电机启动)可承受1.5倍额定值(需参考完整 datasheet),适合长期运行的工业场景。

四、应用注意事项

  1. 负载匹配要求:次级侧输出端需匹配10Ω~100Ω负载电阻(建议根据后端电路需求计算),避免负载过大导致输出电压超限或精度下降;
  2. 安装规范:DIP插件时需确认引脚顺序(避免错焊),与周边高压元件保持≥5mm间距,确保隔离效果不受影响;
  3. 参数限制:禁止初级输入电流超过额定50A(长期过载会导致互感器饱和),如需监测更大电流需串联分流器或选用更高额定值产品。

五、典型应用场景

  1. 工业电机保护:适配11kW以下三相异步电机,用于过载、缺相保护与能效统计;
  2. 光伏系统监测:光伏汇流箱、逆变器的阵列电流检测,实现过流保护与发电效率分析;
  3. 充电桩电流监控:电动汽车充电桩的充电电流实时监测,保障充电安全与计费准确性;
  4. 配电系统分支监测:低压配电柜分支回路的电流检测,辅助负载均衡与故障排查。

总结

FC-SCT1090-200T-50A是一款高性价比的中功率电流互感器,以稳定的转换精度、可靠的隔离安全与易集成的DIP封装,成为工业自动化、新能源领域电流监测的优选器件,可有效解决大电流检测的安全与精度痛点。

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.

The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
