Open-loop hall sensor
Accuracy class: 1
Application:
Industrial control
Energy and automation
AC variable speed drives
Battery supplied applications
Uniterruptable power supplies
Acrel AHKC-EKA Hall Sensor is used to transform the high AC current to small easily manageable values. They are connected with the panel meter or relay and they can help to measure the current or protect the equipment.
Advantage
1. Small package size
2. Low power consumption
3. Extended measuring range

Precautions
1. When the Hall sensor is used, attention must be paid to the coupling between the primary side coil and assistant side coil in order to get better dynamic characteristics and sensitivity, single conductor that should cram the thread hole of Hall sensor module completely is proposed to use.
2. When the Hall sensor is used, the best measuring accuracy can be got under rated input current value. When the measured current is much less than the rated value, the primary side can use multi-turns if want to obtain the best accuracy, that is IpNp=rated ampere-turns. In addition, the temperature of the primary side feeder line cannot be more than 80ºC.
3. When the Hall current sensor is working normally, the auxiliary power supply cannot be more than ±20% of calibration value.
4. The Hall Current sensor is strictly prohibited to be fallen from high place (≥1m) during installation and use.
5. Zero and full scale regulator potentiometer can not be adjusted.
6. Auxiliary power supply is required to be deployed voluntarily.
7. Power positive and negative poles cannot be inversely connected.
