英國PEM CWTUM-F CWTUMHF-F羅氏線圈，具有BNC輸出接口，可連接到大多數(shù)類型的示波器或數(shù)據(jù)采集設(shè)備。CWTUM-F(1.3mm厚度)和靜電屏蔽版本，CWTUMHF-F(1.7mm厚度)是PEM CWT Ultra-mini系列的擴展。新穎的機械結(jié)構(gòu)減小了整體羅氏線圈尺寸，從而減小探頭對被測電路的影響。簡化了密集電力電子電路中的測量。
一、主要特點
1. 新穎的“叉形”結(jié)構(gòu)
線圈長度為55mm
2. 寬工作溫度-40°C至+125°C
3. 額定電流從60Apk到12kApk
4. 線圈絕緣1.3kVpk
5. 峰值di/dt能力高達100kA/us
6. 薄型1.2mm橫截面直徑
高頻帶寬(-3dB)20MHz
7. 屏蔽“HF”版本，橫截面直徑為1.7mm
出色的耐壓能力，高頻帶寬(-3dB)30MHz
二、產(chǎn)品應(yīng)用
1. 電力電子電路中的開關(guān)電流波形，例如：
（1）小至TO-220、D2PAK的MOSFET或IGBT功率器件或其他SMT功率器件
（2）測量半導體中的功率損耗
（3）監(jiān)測小型電感器、電容器、緩沖電路等中的電流
2. 在存在大直流電流的情況下測量小交流電流（例如監(jiān)測電容器紋波）
3. 電源轉(zhuǎn)換器開發(fā)和診斷
4. 測量從工頻到射頻應(yīng)用中的高頻正弦電流、脈沖電流或瞬態(tài)電流
三、標準與合規(guī)性
1. CE 標志
2. 符合 EMC EN61326-1
3. 符合 IEC 61010-1;IEC 61010-2-032 標準
4. PEM Ltd 已通過 ISO9001：2015 標準認證
5. 專利產(chǎn)品
