  使用说明 Directions for use

  1. 电阻R1使传感器输入电流为额定初级电流时传感器有最佳精度,因此传感器应尽量测量与10mA的初级电流相对应的电压。

  The accuracy of sensor will be the best when the current passes through resister R1 and becomes the rated primary current, and therefore the current to be measured by sensor should comply with the primary current 10mA.

  2. 例如:测电压VIN=250V For example, VIN=250V:

  精度(Accuracy )=±0.8%ofVIN(@Ta=+25℃) a) R1=25KΩ/10W,IP =10mA

  精度(Accuracy )=±1.6%ofVIN(@Ta=+25℃) b) R1=50KΩ/ 5W,IP =5mA

  3. 操作范围(推荐的)考虑到初级线圈的电阻(与R1相比,为保持温度差异近可能低)和隔离,此传感器适用于测量电压。

  Considering resistance of primary coil (compared with R1 and temperature difference kept as low as possible) and electrical isolation within measure range (recommended), this sensor is suitable for measuring voltage.
