ACS711EX - Current sensor -31A to +31A
Board with Hall efect sensor.
Current flowing between terminals is isolated from measurement part, but inductes Hall effect which is measured as output voltage proportional to current.
Only 0.6mΩ as a resistance of a chip and double ticness cupper layer cause that losses are very small.
This product is intended for use below 48 V.
Working with higher voltages can be extremely dangerous and should only be attempted by qualified individuals with appropriate equipment and protective gear.
