| Directions for use |
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.
For example, VIN=250V:
Accuracy )=±0.8%ofVIN(＠Ta=+25℃) a) R1=25KΩ/10W,IP =10mA
(Accuracy )=±1.6%ofVIN(＠Ta=+25℃) b) R1=50KΩ/ 5W,IP =5mA
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.
