Description

ACS712 Direct current and alternating sensor 30A with Hall effect technology.

This module based on the ACS712 integrated circuit from Allegro Microsystems allows you to measure the amount of current flowing through an alternating current (AC) or direct current (DC) circuit. The sensing method is through a Hall effect sensor that provides an output voltage proportional to the current flowing in the circuit. The path for the current measurement is through the interior of the integrated circuit and is isolated from the processing circuit.

Main features:

DC operating voltage: 5V
Voltage output without current: VDC / 2 = 2.5V
Sensitivity: 66mV/A
Output Voltage: 0.5V ~ 4.5V (-30A ~ 30A)
Bandwidth 80 kHz
Total error output: 1.5% at room temperature 25°C
Internal resistance: 1.2 MΩ
Minimum insulation voltage 2.1 kVrms
Low offset Hall effect linear sensor.
High measurement precision due to the proximity of the Hall effect sensor to the pitch element (both are inside the IC).
Ability to withstand current peaks up to 5 times the rated operating current.
Dimensions: 31mm x 14mm
