Active Single Phase Voltage Transformer ZMPT101B is a high-accuracy AC voltage measurement module designed to safely sense and measure single-phase AC voltage. It is based on the ZMPT101B precision voltage transformer, which provides excellent linearity, isolation, and stability for voltage detection applications.
The module includes onboard signal conditioning circuitry and a multi-turn potentiometer for fine calibration, allowing accurate voltage scaling according to application requirements. It outputs an analog signal proportional to the input AC voltage, making it easy to interface with microcontrollers such as Arduino, ESP8266, ESP32, and other ADC-based systems.
This module is commonly used in AC voltage monitoring, smart energy meters, power measurement systems, home automation, and protection circuits. Due to its electrical isolation, it ensures safe measurement of high AC voltages while protecting low-voltage control electronics. It is suitable for students, hobbyists, and professionals working on power electronics and energy monitoring projects.
