Description
ZMPT101B AC Voltage Sensor Module
The ZMPT101B AC Voltage Sensor Module is a high-precision voltage transformer designed for accurate AC voltage measurements. It provides galvanic isolation between the high-voltage AC input and the low-voltage output, ensuring safety and reliability. The module outputs an analog voltage proportional to the input AC voltage, making it suitable for integration with microcontrollers and ADCs. Its compact design and adjustable gain via an onboard potentiometer allow for easy calibration and integration into various applications.
Features:
- Measures single-phase AC voltages up to 250V.
- Rated input current: 2mA.
- Onboard micro-precision voltage transformer for accurate measurements.
- Adjustable analog output corresponding to the measured voltage.
- Excellent consistency in voltage and power measurements.
- Active output for easy integration with microcontrollers.
