3PCS 5A Range Current Sensor ACS712 Module AC/DC for Arduino (5A)

3PCS ACS712 Module Current Sensor 5A Range AC/DC for Arduino (5A)

The ACS712 current sensor module provides precise solutions for AC/DC current sensing in industrial, commercial, and communications systems.(Note: there are 3 specifications of the product 5A/20A/30A, Pls choose them accroding to your needs.) Applications: ACS712 Module can be used in motor control, switched-mode power supplies, load detection and management, and overcurrent fault protection ect. Note: ACS712 is based on the principle of Hall detection, please avoid the influence of magnetic field when using it! Description: This module is based on a resistive divider principle design, make the interface terminal input voltage reduced 5 times, for analog input voltage up to 5V, then the input voltage of the voltage detection module can not be greater than 5V × 5 = 25V (if used 3.3V system, the input voltage can not exceed 3.3Vx5 = 16.5V). Because for AVR chips used in 10 AD, so the resolution of the analog module is 0.00489V (5V / 1023), so the voltage detection module detects a minimum input voltage of 0.00489V × 5 = 0.02445V. Features: Current sensor chip: ACS712ELC-05B Power supply:5V Measuring range: ±5 amps Corresponding Analog output:185mV/A. Internal conductor resistance 1.2 mO PCB board dimension:31x13mm Work Temperature: -40°C to 85°C Features: Current sensor chip: ACS712ELC-20A Power supply:5V Measuring range: ±20 amps Corresponding Analog output:100mV/A. Internal conductor resistance 1.2 mO PCB board dimension:31x13mm Work Temperature: -40°C to 85°C Features: Current sensor chip: ACS712ELC-30A Power supply:5V Measuring range: ±30 amps Corresponding Analog output:66mV/A. Internal conductor resistance 1.2 mO PCB board dimension:31x13mm Work Temperature: -40°C to 85°C Voltage input range: DC0-25V Voltage detection range: DC0.02445V-25V Voltage Analog Resolution: 0.00489V DC input connector: Terminal cathode connected to VCC, GND negative pole. Output interface: + 5V or 3.3V - GND
