ACS712-30A Current Sensor

Overview:

The 30A range Current Sensor Module ACS712consists of a precise, low-offset, linear Hall circuit with a copper conductionpath located near the surface of the die. Applied current flowing through thiscopper conduction path generates a magnetic field in which the Hall IC convertsinto a proportional voltage.

Sensing and controlling current flow is a fundamental requirement in a wide variety of applications including,"over-current protection circuits, battery chargers, switching mode powersupplies, digital watt meters, programmable current sources, etc.

• The output voltage at +2 amps would be (2.5V+ (0.066 * 2)) = 2.632 V
• The output voltage at -5 amps would be (2.5V- (0.066 * 5)) = 2.170 V
