Current Sensor Module ( ACS712- 20A)

Description:-

ACS712 Current Sensor Module – 20A can sense up to 20A of current flow. Sensing and controlling the current flow is a fundamental requirement in wide variety of applications, which includes over-current protection circuits, battery chargers, switching mode power supplies, digital watt meters, programmable current sources, etc.  ACS712 Current Sensor Module – 20A is based on ACS712 sensor, which can accurately detect AC or DC current. The maximum AC or DC that can be detected can reach 20A, and the present current signal can be read via analog I / O port of a microcontroller or an Arduino.

Features :

1. The low-noise analog signal path
2. Device bandwidth is set via the new FILTER pin
3. 5 µs output rise time in response to step input current
4. Small footprint, low-profile SOIC8 package
5. 2.1 kV RMS minimum isolation voltage from pins 1-4 to pins 5-8
6. 5.0 V, single-supply operation
7. 66 to 185 mV/A output sensitivity
8. Output voltage proportional to AC or DC currents
9. Factory-trimmed for accuracy
10. Extremely stable output offset voltage
11. Nearly zero magnetic hysteresis
12. The ratio metric output from the supply voltage.

Specifications:-

Supply Voltage: 4.5V ~ 5.5V DC

Measure Current Range: -20A ~ 20A

Sensitivity: 100mV/A
