Product overview

This module measures AC currents of up to 5 A in a contactless method! It has a simple analog
voltage signal as an output interface and has a current to voltage conversion factor of 0,4 V / A. Its
working frequency range is 20 Hz to 20 kHz and it has a dielectric strength of 600 V AC / 1min.
That's some power for a small sensor like this!
