The ACS712 30A Current Sensor is designed to measure both AC and DC currents up to 30A. Using Hall Effect technology, it provides accurate, real-time current measurements with an analog output. Ideal for high-power applications such as motor control, energy monitoring, and battery management
The ACS712 30A is a current
designed to measure larger currents, up to ±30A,
Simple
Comparison:
ACS712 30A:
Measures currents from -30A to +30A.
Key
Differences:
Current Range:
30A version:
For larger currents (heavier devices like larger motors, appliances,
inverters).
Sensitivity:
30A version:
Lower sensitivity, around 66 mV per ampere (since it measures
larger currents, the output voltage change per amp is smaller).
Use Cases:
30A version:
Suitable for higher-power applications, like monitoring large motors,
electric vehicle current flow, or higher power appliances.
Output
Behavior:
sensors output a
2.5V signal when no current flows (zero current).
When current flows:
30A version:
Each 1A changes the output by about 66 mV.
Low-noise analog signal path
Device bandwidth is set via the
new FILTER pin
5 µs output rise time in
response to step input current
Small footprint, low-profile
