Description
Module with a bidirectional Hall current sensor based on the ACHS-7122 system. It allows you to measure the current in the range from -20 to 20 A. The board is powered with the voltage from 4.5 V to 5.5 V and is intended for use in circuits with a logical voltage of 5 V. It offers a current path with low resistance (~ 0,7 mΩ) and electrical insulation up to 3 kV RMS. The output is a proportional analog voltage (100 mV/A) centered at 2.5 V with an error of ± 1.5%.
The sensor requires five connections to work properly: input current (IP+ and IP-), logic power (VCC and GND) and sensor output (OUT). Pin FILTER allows you to adjust the bandwidth of the plate by adding a capacitor to ground in parallel with the 1 nF capacitor that is already on the board. Without an additional external filter capacitor, the frequency response is approximately 80 kHz.
