Hall current sensors are mainly used to isolate and convert Ac,DC,pulse and other complex signals .After signals are convertedaccording to the Hall Effect Theory,the can be directly acquired by AD,DSP,PLC, secondary instruments and other devices.Hall current sensors are widel applicable for acquisition and feedback control of current signals in the current monitoring,battery application,inverter,solar power management,direct current cabinet ,DC motor drive,electroplating,welding,frequency converter,UPS servo control systems.They feature the quick response ,wide range of measurement,high precision ,strong overload capcity,good linearity and excellent and anti-interference performace.

+15V—— power supply+15V

-15V ——power supply-15V (Note that power positive and negative poles cannot be inversely connected.)

M —— signal output end positive pole

G —— power ground and signal output end negative pole

Note: The specific wiring is subject to the terminal no. of object shell. 5. 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 80℃. 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. 6. Order Sample
