Perfect for high current monitoring

Used the 100A version for my EV battery project. The output is very stable and linear. Easy to interface with Arduino.

Solid performance at 200A

Testing the 200A variant. It stays cool even under continuous load. Just ensure your PCB traces can handle the current.

Great value for money

Much cheaper than buying the breakout boards from other vendors. Soldering the SOIC package required some skill but worth it.

Fast response time

The 3us response time is accurate. Great for capturing transient spikes in my power supply testing rig.

Reliable industrial grade sensor

We integrated these into our motor controllers. The isolation is excellent and it handles noise very well in high-power environments.

Good accuracy, needs calibration

Works well for my solar inverter setup. Had to do a quick calibration in software to get exact readings, but overall very satisfied.

5 FAQ

Q: Does this module come with a pre-soldered header?

A: No, this listing is for the raw sensor module component. Headers are not included and must be soldered by the user.

Q: What is the sensitivity for the 50A version?

A: For the 50A range, the typical sensitivity is 80 mV/A. Please refer to the datasheet for specific tolerance details.

Q: What is the maximum working voltage for isolation?

A: The sensor provides basic isolation rated for up to 2100 V RMS, suitable for most low to medium voltage applications.

Q: Is the output ratiometric to the supply voltage?

A: Yes, the output is ratiometric. This means the zero-current output and sensitivity scale proportionally with the supply voltage.

Q: Can this measure AC and DC current?

A: Yes, the ACS758 uses Hall Effect technology which allows it to measure both AC and DC current accurately.
