The ZMCT103C AC current transformer module can be used to monitor current in various applications. This module is based on the ZMCT103C IC. The mechanism of this IC is that the wire whose current is to be measured, passes through the hole of the IC. Then, according to AC current, voltage is induced on both sides of the IC.

In this module, the output voltage of ZMCT103C IC is amplified by a series of amplifiers and can be used as the module output. The module outputs an analog AC voltage corresponding to AC current of the wire passing through the module hole.
