Special Features

  • 【Adjustable Analog Voltage Output】This module is capable of measuring AC voltages up to 250V, providing an adjustable analog output that corresponds to the measured voltage levels.
  • 【Sine Wave Output Signal】It outputs a sine wave signal, with the waveform's median value (DC component) being equivalent to half of the supply voltage (1/2 VCC).
  • 【ZMPT101B Series Integration】The single-phase AC active voltage mutual inductance module comes with the ZMPT101B series high-precision voltage transformer and a high-precision operational amplifier circuit. This setup simplifies the acquisition of AC power signals within 250V.
  • 【High-Precision Amplifier Circuitry】The on-board amplifier circuit is designed for high precision, performing exact signal sampling, appropriate compensation, and other essential functions for accurate voltage measurement.
  • 【Miniature Voltage Transformer】The module features a precision micro voltage transformer for converting high voltage signals into a measurable range. It operates with a supply voltage of 5-30V.

Description

Product Description:

1. When L, N is connected to AC220V. VCC, GND input DC5V-30V. OUT, GND connected to the oscilloscope can get a sine wave.

2. Adjust the potentiometer can change the amplitude of the output waveform (the middle value will not change during the adjustment process), the waveform of the range of 0-VCC.

3. If the waveform is distorted in the process of increasing the amplitude, it can be solved by appropriately increasing the operating voltage VCC. If you want the middle value of the waveform to move to 0 o'clock, you can connect a capacitor of about 105pF in series with OUT to filter out the DC component in the waveform.

Package Includes:

4 x Voltage Transformer Module
