ACS712 30A Current Sensor Module

ACS712 30A Isolated Hall-Effect Current Sensor Module

The Allegro ACS712 provides economical and precise AC or DC current sensing in industrial, commercial, and solar systems. The internal conduction path is galvanically isolated up to 2.1 kV RMS from the sensor leads, enabling safe high-side current measurement without optoisolators.

Specifications

• Current Measurement Range: -30A to +30A (bidirectional AC and DC)
• Sensitivity: 66 mV per Ampere (centered at 2.5V at zero current)
• Dielectric Isolation: 2.1 kV RMS minimum between copper path and logic pins
• Bandwidth: 80 kHz (filter pin allows external capacitor noise filtering)
• Operating Voltage: 5.0V DC (VCC)
• Low Resistance Internal Conductor: 1.2 mΩ internal copper trace resistance
