ZMCT103C Single Phase AC Current Transformer Module – 5A Range

The ZMCT103C module is a high-precision AC current sensor designed for accurate signal sampling in single-phase systems. Equipped with the ZMCT103C series miniature current transformer and a precision operational amplifier circuit, this module provides a reliable solution for monitoring AC currents up to 5A.

Thanks to its onboard op-amp circuitry, the analog output signal can be fine-tuned using the onboard potentiometer, allowing amplification up to 100 times. The maximum output voltage is limited to half of the supply voltage (VCC/2), ensuring safe and stable operation.

Ideal for energy monitoring, power measurement, and other AC signal acquisition applications, this module is compact and easy to integrate into a variety of electronic projects.
