About this item

  • The module can measure AC voltage within 250V and the corresponding analog output can be adjusted.
  • The output signal is a sine wave, and the median value of the waveform (DC component) is 1/2 VCC.
  • Single-phase AC active output voltage mutual inductance module equipped with ZMPT101B series of high-precision voltage transformer and high-precision op amp current, easy to 250v within the AC power signal acquisition
  • high-precision on-board amplifier circuit, the signal to do the exact sampling and appropriate compensation and other functions
  • Onboard precision micro voltage transformer. Supply voltage: 5-30v


Product description

Instructions:

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.
