台湾标准电机SEW仪器仪表--890 PR Phase Sequence Indicator

    
 
890 PR   Phase Sequence Indicator
890 PR
FEATURES
 
 The 890 PR is a Non-Contact Phase detector with flashing LEDs and beeping buzzer to show the detection of AC 3-phase sequence.
 Two functions in one unit, including open phase and phase sequence.
 Clipping the right 3-phase lines (up to color) over the jacket with non-contact sensor clips which promote safety of measurement.
 Brightness switch is convenient to make the indication visible in dim areas or sunlight.
 Back cover magnet fix the instrument onto the AC distribution panel offer easy measurement.
 3-Phase AC 75 to 1000V is fitted for detection.
 Detect frequency range is from 45 to 65 Hz.
 Safety standard :
  CAT III 1000V/CAT IV 600V.

特 點
1. 890PR是非接觸式量測的檢相計，它藉由LED的顯示和蜂鳴器的聲音，來查驗三相交流
電壓系統的狀況。
2. 具有檢測相位和相序的雙重功能。
3. 自動關機功能(約五分鐘)。
4. 鱷魚夾上有顏色貼紙區分，由於採用不接觸裸銅檢測，只要將鱷魚夾夾住電源線外部
即可檢測，因此安全度高。
5. 具有C亮設計，可在強光下或昏暗處辨識檢測狀況。
6. 儀表背面附有四顆強力磁鐵，可懸掛於配電箱外殼，方便操作人員使用。
7. 應用電壓及頻率寬廣，分別為75V~1000V交流 電壓45~65Hz。
8. :
CATⅢ 1000V/CATⅣ 600V
