Hall current sensors are mainly used to isolate and convert AC, DC, pulse, and other complex signals. Signals converted by the hall effect can be directly acquired by AD, , PLC, secondary meters, and other devices. Hall current sensors are widely applicated for the 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, and UPS servo control systems. They feature quick response, a wide range of measurements, high precision, strong overload capacity, good linearity, and excellent anti-interference performance. Rated Input: 0-500A DC or 0-500A AC. Rated Output: 0-5/4Vdc. Aperture: 20mm. Power Supply: 12-15Vdc. Accuracy: Class 1.0. Response Time: 5us. Installation: Clamp-on (Split-core) measuring cable and screw fixed on the panel. Appearance: Small package size, Low power consumption, Extended measuring range It is insulative between the primary and secondary grade of the AHKC- series current sensor which can be used for measuring pulse current. Wiring of Auxiliary Power Supply Input&Transduced Signal Output 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, the single conductor should cram, the threaded hole of the Hall sensor module completely is proposed to use. 2. When the Hall sensor is used, the best measuring accuracy can be got under the 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 the calibration value. 4. The Hall Current sensor is strictly prohibited to be fallen from a 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.
