AHKC-BS series closed-type Hall current sensor is a new generation of current sensor developed by applying the principle of the Hall effect.
It can measure the current of DC, AC, pulse, and various irregular waveforms under the condition of electrical isolation.
The product meets the industry standard: JB/T7490-2007 
HALL open-loop current sensor
★ Technical features:
(1) Small volume
(2) Wide measuring range
(3) Light weight
(4) Low power consumption
(5) No insertion loss
★ Working principle:
After the magnetic field generated by the primary current IP is concentrated through the magnetic core, the HALL induction chip is used to induce the size and direction of the primary current IP at the air gap of the magnetic core. The output voltage of the HALL induction chip passes through the signal processing circuit, so that the output of the sensor can accurately reflect the magnitude of the measured current. In order to improve the performance of the HALL open-loop sensor, silicon steel or permalloy is usually used as the material of the magnetic core. When the operating frequency of the measured current is greater than 10kHz for a long time, the sensor may be damaged by the heating of the magnetic core.
Take a photovoltaic DC cabinet as an example, take the photovoltaic DC cabinet need to monitor the output current and voltage of 8-channel photovoltaic combiner boxes as an example, since the general collector in the photovoltaic DC cabinet is connected with bronze medals and the cabinet space is limited, it is recommended to use 8 The smaller AHKC-BS 200A/5V Hall open-loop current sensor, combined with the Ankerui DC cabinet collection device AGF-D, can calculate the real-time output current of the front-stage 8-channel combiner box, and can be matched with a DC high voltage voltage The sensor ACTDS-DV/V realizes power and energy measurement.
