§ 02 — Description
Analog current measurement module based on the Allegro ACS712ELCTR-05B-T Hall-effect sensor, designed for monitoring energy consumption, protecting circuits from overload and monitoring motor operation.
High safety and isolation: Measurement is based on the Hall effect, which provides built-in galvanic isolation of the measuring circuit from the power section with voltages up to 2.1 kV.
Bidirectional measurement: Capable of measuring both direct current (DC) and alternating current (AC) in the range from -5A to +5A.
Easy connection: The power circuit is connected in series with the load through a convenient screw terminal block, and the output signal is read through a single analog pin of the microcontroller.
