ZMCT103C Single Phase AC Current Transformer Module - 5A Range

The ZMCT103C unit is a high-precision AC current sensor, engineered to accurately sample signals in single-phase systems. It is equipped with a mini current transformer from the ZMCT103C series and a precise operational amplifier circuit, providing a reliable solution for monitoring AC currents up to 5 amperes.Thanks to the integrated operational amplifier circuit, the analog output signal can be precisely adjusted using the built-in voltage scale, allowing for amplification up to 100 times. The maximum output voltage is limited to half the supply voltage (VCC/2), ensuring safe and stable operation.This unit is ideal for power monitoring, power measurement, and other AC current signal acquisition applications. It is compact in size and easy to integrate into a variety of electronic projects.
