NOYITO Voltage Transformer Module Active Single Phase Output Voltage Sensor Module - Measure 0-250V AC Voltage - Output Sine Wave Adjustable

Parameter:
Product Name: On-board precision voltage transformer.
Op amp circuit: On-board high-precision op amp circuit, accurate sampling and proper compensation of signals.
Analog voltage output: The module can measure AC voltage within 250V and the corresponding analog output can be adjusted.
Output signal: The output signal is a sine wave, and the median value of the waveform (DC component) is 1/2 VCC.
Module supply voltage: 5-30V.

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.
