Whadda WPSE323 ACS712 Current Sensor Module

The Whadda WPSE323 ACS712 Current Sensor Module provides a precise and cost-effective solution for measuring both direct (DC) and alternating (AC) current in a wide range of industrial and commercial electronic systems. Based on the reliable Allegro® ACS712 sensor, this module's straightforward design ensures easy implementation and seamless integration into your projects, offering robust performance without complexity.

Engineered for accuracy, the module features a linear measurement range of -20 to +20 Amps, making it suitable for monitoring significant current flows in both directions. It operates on a 5V DC supply and outputs an analogue voltage that is proportional to the measured current, with a precise scale factor of 100mV per Ampere. At zero load, the output voltage defaults to VCC/2, providing a clear reference point for your readings.

Typical Applications

This versatile sensor is ideal for numerous critical applications, including motor speed and load control systems, inrush and load detection management, the monitoring and protection circuits within switching power supplies, and as a key component in overcurrent fault protection systems. Its reliability makes it a fundamental tool for developing safer and more efficient electrical designs.
