Description

Specification:
Item Type: Voltage Sensor Module
Voltage transformer: On-board precision miniature voltage transformer
Op amp circuit: On-board high-precision operational amplifier circuit, accurate signal sampling and appropriate compensation functions
Analog voltage output: The module can measure AC voltage within 250V, and the corresponding output analog quantity can be adjusted output signal
Signal output: Sine wave, the middle value (DC component) of the waveform is 1/2VCC
Power 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 oclock, you can connect a capacitor of about 105pF in series with OUT to filter out the DC component in the waveform.
