AC Voltage Sensor

SENSING PRINCIPLE: Operates using a precision ZMPT101B miniature voltage transformer that senses AC voltage and converts it into a proportional low-level analog signal while maintaining electrical isolation.
SENSOR STRUCTURE: The module contains a ZMPT101B precision voltage transformer, signal conditioning circuit, and a high-precision operational amplifier for accurate voltage sampling and compensation.
PIN CONFIGURATION: VCC (Power supply), OUT (Analog signal output), GND (Ground), GND (Ground reference).
OUTPUT SIGNAL: Provides an adjustable analog output signal proportional to the measured AC voltage waveform.
OPERATING RANGE: Capable of measuring AC voltage up to approximately 250V with proper calibration.
SIGNAL CONDITIONING: Integrated high-precision operational amplifier circuit ensures accurate signal sampling and stable waveform processing.
SENSITIVITY ADJUSTMENT: Includes an onboard potentiometer that allows calibration of the output signal for improved measurement accuracy.
MODULE DIMENSIONS: Compact PCB module measuring approximately 3 cm × 2 cm × 1 cm with a lightweight design around 5 grams.
APPLICATION SCOPE: Commonly used in AC voltage monitoring systems, energy meters, electrical measurement devices, overload detection systems, relay protection circuits, household electrical equipment, and industrial power monitoring applications. ⚡
