ZMCT103C 5A Range Single-Phase AC Current Transformer Sensor Module
The ZMCT103C 5A Range Single-Phase AC Current Transformer Sensor Module is a compact and highly accurate AC current sensing module designed for measuring single-phase alternating current up to 5A. Built around the precision ZMCT103C micro current transformer, it provides an isolated analog output proportional to the measured AC current, making it ideal for energy monitoring, power measurement, overload detection, and smart metering applications.
The module features an onboard precision amplifier and signal conditioning circuit that enables reliable current sampling with excellent linearity and electrical isolation. It can be easily interfaced with popular microcontrollers such as Arduino, ESP32, STM32, Raspberry Pi (via ADC), and other embedded systems for real-time current monitoring. Its compact size, adjustable output, and low-cost design make it suitable for DIY projects, industrial automation, home energy management, and IoT-based power monitoring solutions.
